What is a solution with a pH of 2.2 acidic basic or neutral?

pH = 2.2 is VERY Acidic.

The pH range is 0 to 14.

pH from 0 to 6 is acidic

pH = 7 is neutral (water)

pH from 8 to 14 is basic.

'pH' means the' negative logarithm , to the base '10', of the hydrogen ion concentration ' .

Mathematically it is

pH = -log(10) [H^(+)]

Inverting

[H^(+)] = 10^(-pH)

So for a pH = 2.2

[H^(+)] = 10^(-2.2) = 0.0063....
