You have two solutions, A and B. The pH of solution A is 6 and pH of solution B is 8. Which solution has more hydrogen ion concentration? Which of this is acidic and which one is basic?

Explanation

pH of solution A=6
`thereforeH^(+)` ion concentration `=10^(-6)M`
pH of solution B=8
`thereforeH^(+)` ion concentration `=10^(-8)M`
As `10^(-6)gt10^(-8)` , hence solution A has more `H^(+)` ion concentration .
A solution with `pHlt7` is acidic .Hence , solution A is acidic .
A solution with `pHgt7` is basic .Hence , solution B is basic .
