What effect does the concentration of $H^+_{(aq)}$ ions have on the nature of the solution ?
Concentration of $H^+_{(aq)}$ can have a varied effect on the nature of the solution. With an increase in $H^+$ ion concentration, the solution becomes more acidic, while a decrease of $H^+$ ion causes an increase in the basicity of the solution.
What is a neutralisation reaction? Give two examples.
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?
