Is there some kind of trick or way to find the answer?
Predict whether the following salt solutions are neutral,
acidic, or basic, and calculate the pH of each. Hint: Write the
equation for dissociation of the salt and any equilibrium
established.
0.25 M NH4Br; KB of NH3 = 1.8×10−5 0.10 M NaCN;
KA of HCN = 4.9×10−10 0.20 M NaNO2;
KA of HNO2 = 4.6×10−4
