How to predict whether the aqueous solution for the following salts are acidic , basic or neutral (a)NH4Br (b)KClO4 (c)NaHC2O4 (d)CsBr (e)KHSO4 (f)[CH3NH3]Cl?
You have weak acids, ammonium bromide, sodium oxalate, potassium bisulfate, and ammonium bromide. And neutral salts: potassium perchlorate, and caesium bromide. The only potential problem is sodium oxalate.
The parent acid, oxalic acid, has
Another way to look at this is by the strong acid/weak base formalism. Since we are chemists, physical scientists (hopefully!), I would always prefer to get the numbers, and find the
