Consider an aqueous solution that is 0.050 M in H2Se (Ka = 1.29 x 104) and 0.075 M in NaHSe. Out of the answer choices below, which is the only pH that could possibly be correct? (NOTE: The correct answer may or may not be the actual pH of the solution.) 1.29 2.56 3.88 4.30

Determine the pH of a 0.10 M solution of sodium acetate (CH3COONa) at 25°C. (Ka of acetic acid = 1.8 ×10−5.) pH =

Calculate the pH of a solution that’s 0.65 M in NaNO2 and 0.40 M in HNO2. (HNO2, Ka = 4.45 × 10–4 ).

What is the pH of an aqueous solution with [H3O+] = 2×10−14 M? Express the pH numerically using one decimal place.

Four solutions of an acid dissolved in water are sketched below, as if under a microscope so powerful individual atoms could be seen. The same volume of solution is shown in each sketch. Rank the solutions by the strength of the dissolved acid. That is, select 1 under the solution of the strongest acid, 2 under the solution of the next strongest acid, and so on.
