Could someone please help me on this.

I just cant write them.

I'm using a lecture slide from the internet.

I want to know how to write them for Na₂HPO4 and Benzoic acid

The lecture slide above does explain but I don't really understand.

Thank You Very Much

You should describe what happen if you dissolve the material in water.

You take the Anion of the Hydrogenphosphate and add water. The solution is alcaline as hint.

What general group do Organic acids have? Add to this water as well.
