Maalox Chemical Reaction

The experiment is to observe a variety of chemical reactions and to identify patterns in

“The pH of a solution is a measure of the molar concentration of hydrogen ions in the solution and as such is a measure of the acidity or basicity (sic) of the solution. The letters pH stand for power of hydrogen and the numerical value defined as the negative base 10 logarithm of the molar concentration of hydrogen ions.” (PH, 2002). The pH scale is from 0 to 14. When the pH is higher, the hydrogen ions are fewer and the substance considered alkaline. This means when a pH unit increases by one, there is a tenfold change in the hydrogen ion. For example, if a substance has a 7 pH, it has 10 times as many as hydrogen ions available as 8 pH. A lake having a water pH between 6.5 and 8.5 is considered to be neutral. Researchers tested Peckham Park lake water monthly from August 2015 to April 2016 for water pH levels. A water quality PH test strip taken from a jar and dipped into the lake. After a few minutes, the strip will turn a color and this color determines the pH. The jar the strips came in has a chart of the colors on the back which compared to the color on the strip. The lake tested monthly using the PH test strips, which show the pH level, hardness, toxic, etc. using color-change

pH is also known as a measure of hydrogen ions in a solution. A hydrogen ion is the nucleus of a hydrogen atom being split from its electron. Studying the pH of different types of soil being placed in a control group such as tap water will represent the acidity or alkalinity of the matter. The pH scale begins at 0 and goes all the way up to 14, pH 7 being its neutral point, which isn’t acidic or basic. A neutral point on the acidic scale is in the middle, anything lower than the neutral point (7), is acidic, and anything higher than the neutral point is considered basic or “alkaline”.

Acids are a corrosive substance with a pH less than 7. Acidity is caused by a high concentration of hydrogen ions.

In the experiment the magnesium reacts with the hydrochloric acid to create magnesium chloride and hydrogen. The balanced formula for this is:

To see if the concentration of hydrochloric acid will increase the rate of the reaction between magnesium ribbon and hydrochloric acid.

Knowledge Probe: According to.epa.gov/acidrain/measure/pH.html, pH is a measure of the hydrogen ion concentration of a solution. Solutions with a high concentration of hydrogen ions have a low pH and solutions with a low concentrations of H+ ions have a high pH. A pH of 7 is the most neutral you can get and 0 being the most acidic and 14 being the most basic. each level is 10 times more basic/ acidic than the previous level, for example a pH of 8 is 10 times more basic than 7, and a pH of 9 is 100 times more basic than 7. when an acidic substance reacts with a basic substance they counter each other like mixing hot and cold water.

(Healthline) (Transition: So, you may be asking, what’s the big deal about alkaline foods?) III. Alkalinity is on the opposite spectrum of the pH scale, they “balance out” the acidity of the body and are a 7.1-14 on the pH scale.

When testing the homemade pH paper the results of the experiment show the pH paper is more susceptible to acidic chemicals than to alkaline chemicals. For example, rubbing alcohol that has high alkalinity was not able to be sensed by the pH paper. Although, acidic chemicals such as vinegar and dish detergent are easily sensed by the pH paper.

In the synthesis reaction of Barium Carbonate, a solid, BaCO₃, is formed. This reaction is demonstrated by the formula Ba+CO₃ → BaCO₃. Another example of a precipitate forming and indicating a chemical reaction, is shown by the shells of mussels and clams. The clam or mussel’s solid shell, which acts as the precipitate, is formed from chemicals from the sea water combining with chemicals from the creature, be it the clam or mussel. Basically, if a reactant produces a product that forms a solid, such solid, the precipitate, is sufficient evidence that a chemical reaction has

I also learned that pH scale is measured either with litmus paper, you dip in the substance and measure that color to a acidity color

Ph means Potential of Hydrogen. The pH scale is used to measure the acid-base level. If the level is between 0 and 6 is acid. If it is 7 it is neutral. And if between 8 and 14, a solution is basic, or alkaline. The pH of a healthy person is in the range of 7.35 to 7.45, therefore alkaline. When a concentration of hydrogen ions is not normal, the kidneys eliminate acid or alkaline urine as needed, contributing to a regulation of the concentration of hydrogen ions. The renal mechanism of regulation causes the concentration of bicarbonate ions in the blood to vary, through reactions that take place in the renal tubules. It is the definitive mechanism of adjustment in most acid-base imbalances of metabolic origin. The higher the pH, the more alkaline

Results and Discussion: The first process of the experiment was when 1.0545 grams of the pieces of aluminum cans were mixed with potassium hydroxide to form the products potassium aluminum sulfate and water. The equation shown below is the unbalanced version Al(s)+KOH(aq)+H2O(l)KAl(OH)4(aq)+H2(g) .The new balanced equation was 2Al(s)+2KOH(aq)+6H2O(l)2KAl(OH)4(aq)+3H2(g). The reaction shown above is a redox reaction due to the transfer of electrons from one element to another.The aluminum was oxidized from 0 to 3+ and the hydrogen in potassium hydroxide was reduced from 1+ to 0. As the reaction was being completed a gas was formed as well as a color change in the liquids used. In order to speed up the reaction a hot plate was used. All of this was done under a fume hood to make sure none of the gases formed was in the air. The next chemical process in the experiment was when the 20 mL of sulfuric acid was added to the solution. The balanced equation is 2KAl(OH)4(aq)+H2SO4(aq)2Al(OH)3(s)+K2SO4(aq)+2H2O(l) but the total ionic equation is what was used which was Al(OH)4-(aq)+H+(aq)Al(OH)3(s)+H2O(l). The reaction shown was an acid-base

    In the addition of 3 mL of ammonia to the precipitate, the solution or precipitate were unchanged and no visible chemical reaction took

The earliest definition of an acid came from a Swedish chemist named Arrhenius, who defined an acid as a substance that produces hydrogen ions, which are in fact hydronium ions (H3O+), when dissolved in water, and a base, the complementaries of acids, as a substance that produces hydroxide ions (OH-) in water. Definitions from other scientists such as Brønsted-Lowry expanded on this range and defined acids as proton donors and bases as proton acceptors, with the most expansive definition coming from G.N. Lewis, who defined acids as electron pair
