Calculate the percent ionization of a 6.7 M weak acid solution in water. (Ka = 3.7 × 10–4) Write the answer with 2 decimals. Show your calculations in the CALCULATIONS assignment.
Classify each acid as strong or weak. If the acid is weak, write an expression for the acid ionization constant (Ka). If the acid is polyprotic, classify both ionizations. a. HF b. HNO3 c. H2CO3
Question 1 : HA is a weak acid. Its ionization constant, Ka, is 1.2 x 10-13. Calculate the pH of an aqueous solution with an initial NaA concentration of 0.075 M. Question 2 : We place 0.143 mol of a weak acid, HA, in enough water to produce 1.00 L of solution. The final pH of the solution is 1.28 . Calculate the ionization contant, Ka, of HA. Question 3 : We place 0.661 mol of a weak acid, HA,...

Write the equations that represent the first and second ionization steps for selenous acid (H2SeO3) in water. (Use H3O+ instead of H+.) First Ionization Step Second Ionization Step
For a generic weak acid HA, the ionization into H+ and A in water is not complete: HA (aq) =H+ (aq) + A (aq) a. Show that the acid dissociation constant of the acid, Ka, can be obtained from the degree of dissociation a using the following formula: a2 Ka 1-a b. The freezing-point depression of a 0.010 m acetic acid solution is 0.0193 K. From this data, what is the acid- dissociation constant K of acetic acid?
