The phenolphthalein pH indicator is clear and colorless in an acidic solution, but it turns a pink in a basic solution. Knowing this, you examine two clear and colorless solutions. One, you are told is acidic and the other is basic. Furthermore, you are told that the acidic solution contains phenolphthalein. So which is which? You don’t know because both solutions are colorless. To find out, you add a drop of Solution 1 to Solution 2. A pink color appears for a moment, but then disappears. This tells you that   Select one: a. you now need to try adding Solution 2 to Solution 1. b. Solution 2 is acidic. c. Solution 1 is acidic. d. both solutions are now neutralized.

A solution has a pH of 1. This is considered a highly acidic solution and a solution that has a pH of 14. This is considered a highly basic solution. Explain

A weak acid is dissolved in water to generate a solution that is 0.100 M. The pH of this solution is measured to be 4.25. What is the Ka of the weak acid?

How is calculating pH of a salt different than a calculating pH of a weak acid or base ?

Type your anSwers in all of the Let's consider two dilute acid solutions that are both made at a concentration of 0.010 M. One solution is made with HCl and one solution is made with HClO. Complete the following sentences based on these two solutions. HCl is a Type your answer here acid while HCIO is a Type your answer here acid. (strong, weak) The pH of the HCl solution is Type your answer here Due to the difference in acid strength, HCIO dissociates Type your answer here than HCl. (more, less) This means that there is Type your answer here (more, less) Htor H.0t produced in the HCIO solution than in the HCl solution. Higher hydronium ion concentration corresponds to a Type your answer here pH value. (higher, lower) Altogether, this means that the pH of the HCIO solution is Type your answer here than the HCl solution. (higher, Fullscreen lower) 10:40 PM a の 5/8/2021 hp enter pause ↑ shift end

A solution contains 0.145 M ammonium chloride and 0.108 M ammonia. The pH of this solution is

1. What is the hydrogen ion concentration of a solution whose pH is 9.36? What is its hydroxide ion concentration? 2. Rank the following in order of increasing acid strength, and explain your reasoning. hydrofluoric acid, acetic acid, nitric acid, hypoiodous acid

Acidic Basic Neutral HC4H4O6- CO32- Na+ NH4+ HPO42- CI- Zn2+ PO43- NO3 Fe3+ HCO3- Ca2+ H2PO4- K+ In the above table are some ions that have been categorized as acidic, basic or neutral after making pH measurements, similar to how we conducted this experiment. It is expected firstly that neutral ions are conjugates of strong acids or bases, secondly that acidic ions are cations and thirdly that basic ions are anions. Do the above data support these expectations? Identify and discuss any apparent exceptions.

Enough of a monoprotic weak acid is dissolved in water to produce a 0.0147 M solution. The pH of the resulting solution is 2.31. Calculate the Ka for the acid.

A solution decreases the alkalinity of another solution . Does the property describe a solution that is acidic , basic , both or neutral?
