Okay - here's an easy way to go through these. In this context, acids are made up of an anion and hydrogen atoms (H+), and bases are made up of cations and hydroxide ions (OH-)

Simply split your salt into the cation and anion, and accordingly add your H+ or OH-.

Let's take a) as an example.
NaCl becomes Na+ and Cl-.
To balance the charges, we simply add accordingly. We give Na+ the OH- to give you NaOH (sodium hydroxide), and we give Cl- the H+ to give you HCl (hydrochloric acid). Try the rest!
