1. 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?

Solution A has more hydrogen ion concentration.
Solution B has more hydrogen ion concentration.
Both solution A and B have more hydrogen ion concentration.

2. What effect does the concentration of $H^+$ ions have on the nature of the solution?

It becomes basic when the concentration of $H^+$ ions increases.
If the concentration of $H^+$ ions decreases it becomes basic.
It becomes basic when the concentration of $H^+$ ions equal to $H_3O^+$ ions.
If concentration of $H^+$ ions increases it becomes acidic.
