Hint: We will probably need to convert pOH to pH or find [latex]\left[{\text{H}}_{3}{\text{O}}^{\text{+}}\right][/latex] using [OH] in the final stages of this problem. Determine if the following salt is neutral, acidic or basic. I Use 4.0 [latex]\times [/latex] 1010 as Ka for HCN. Determine whether aqueous solutions of the following salts are acidic, basic, or neutral: Consider each of the ions separately in terms of its effect on the pH of the solution, as shown here: If we measure the pH of the solutions of a variety of metal ions we will find that these ions act as weak acids when in solution. I've prepared a number of aqueous calcium chloride solutions from distilled water, all of which are purple in the presence of universal indicator and tested with a calibrated $\mathrm{pH}$ probe to be basic. Whichever is stronger would decide the properties and character of the salt. San Francisco: Pearson Education, 2007. A salt in which the cation is the counterion of a strong base and in which the anion is the conjugate base of weak acid form basic solutions. K+ will not hydrolyze, but the CN- anion will attract an H+away from the water: \[CN^-_{(aq)} + H_2O_{(l)}\rightleftharpoons HCN_{(aq)} + OH^-_{(aq)}\].
