NH4CN - salt from a weak acid (HCN) and a weak base (NH3) - pH will depend on the Ka and Kb. It is also useful to have memorized the common strong acids and bases to determine whether KCl acts as an acid or base in water (or if it forms a neutral solution).Note that we are talking about whether KCl is an acid, base, or neutral when dissolved in water.- Salts of strong bases and strong acids: pH will remain neutral at 7.- Salts of weak bases and strong acids: pH less than 7 (acidic).- Salts from strong bases and weak acids: pH greater than 7 (alkaline). alright, I saw in a couple places that CH3NH3Br and CH3NH3Br were salts of CH3NH2 and HBr/HCl but they were probably just wrong. Apart from the mathematical way of determining pH, you can also use pH indicators. Calculate the pH of a buffer formed by mixing 85 mL of 0.16 M formic acid (HCHO2, Ka= 1.8x10-4 with 94 mL of 0.15 M sodium formate (NaCHO2).)
