Question

what happens when ph of the aqueous solution decreased from 5 to 4 what is the nature of the solution​

Answer 1

Answer:

IT BECOME ACIDIC

Explanation:

If you add acid to a solution the concentration of hydrogen ions (acidity) increases and the pH decreases. Frequently people confuse pH with acidity—pH is the scale on which acidity is expressed, but it is not synonymous with acidity.A solution with a high number of hydrogen ions is acidic and has a low pH value. A solution with a high number of hydroxide ions is basic and has a high pH value.
