Answer 1

if the concentration of H^+ ion is more then the solution is acidic if it is less then it's basic. yes, basic solutions have H^+ ions but in a very low concentration and they are basic because the concentration of OH- ions is more

Answer 2

$\huge\mathfrak\purple{Here's\:ur\:answer}$

The concentration of H+ (aq) ions determines the acidic nature of solution. Hence, acidity of a solution increases with increases in concentration of H+ (aq) ions and vice versa.

When a base is dissolved in water then it will produce H⁺ ions as wells as OH⁻ ions. if H⁺ ion concentration is more than OH⁻ ion then the solution is acidic. And they show basic character if OH⁻ ion concentration is more than H⁺ ion concentration.That means they are basic due to presence of more OH- ions.
