Some soluble compounds are listed in the table below. Complete the table by filling in the name or chemical formula of each compound, whichever is missing. (If there is more than one way to name the compound, choose the name used when the compound is dissolved in water.) Also classify the compound using the checkboxes. compound 0 Ba(OH)₂ HCH₂ CO₂ name ammonia 0 potassium bromide type of compound (check all that apply) strong weak strong weak base base acid acid ionic molecular 0 0 0 X 5

Please solve the question step by step and way with the correct answer.

From the options below, select the three (3) methods that could be used to form a buffer solution: Select 3 correct answer(s) Adding a strong base to a weak acid solution Adding a strong base to a weak base solution Adding a strong acid to a weak acid solution Adding a weak acid (or weak base) to a solution of a salt of that weak acid (or weak base) Adding a weak acid (or weak base) to any salt solution Adding a strong acid to a weak base solution

The solution started out clear, but when the 12 M HCl was added, lots of the white solid formed. The second round of the eight drops of HCl were added, which produced more white solid taking up most the volume of the test tube. Using the equation and Le Chatelier’s principle, what happened when the HCl was added to the reaction?

Human blood has a pH of approximately 7.4 due to the carbonic acid/bicarbonate ion (H2CO3/HCO3−) buffer system. Any pH changes below 6.8 or above 7.8 can lead to death! Carbonic acid dissociates to form water and carbon dioxide in the equilibrium shown below. This process is crucial in respiration. H2CO3 (aq) ⇋ CO2 (g) + H2O pKa1 = 2.77 Carbonic acid dissociates in water to form the bicarbonate ion and the hydroxonium ion by the following equilibrium reaction:H2CO3 (aq) + H2O ⇋ H3O(aq)+ + HCO3− pKa2 = 3.70    (i) If there is a 25% increase in carbonic acid levels as per pKa1, explain how the body would deal with this change.

+ pH Changes in Buffers When a solution contains a weak acid and its conjugate base or a weak base and its conjugate acid, it will be a buffer solution. Buffers resist change in pH following the addition of acid or base. A buffer solution prepared from a weak acid (HA) and its conjugate base (A) is represented as HA (aq) → H¹ (aq) + A (aq) The buffer will follow Le Châtelier's principle. If acid is added, the reaction shifts to consume the added H+, forming more HA. When base is added, the base will react with H+, reducing its concentration. The reaction then shifts to replace H+ through the dissociation of HA into H+ and A™. In both instances. [H] tends to remain constant. The pH of a buffer is calculated by using the Henderson-Hasselbalch equation: A] pH =pK₂ +log HA ▼ Part A pH = What is the pH of a buffer prepared by adding 0.607 mol of the weak acid HA to 0.507 mol of NaA in 2.00 L of solution? The dissociation constant K₁ of HA is 5.66 x 10-7 Express the pH numerically to three…

Fill in the blanks to show how you would solve for the pH of a 0.10 M aqueous solution of the weak acid HA. For the table and the equilibrium expression, do not ignore x. 0.10 POH Initial Concentration (M) Change 0.10 - X Equilibrium 2x² K₂ = 0.10 - 2x 4x² HA(aq) X (0.10 - x)² + 2x (0.10-2x)² H₂O(l) + +
