What is the pH of [H+]=0.0000000035 and is it acidic, basic, or neutral?
natima [27]

Answer:

The pH is 8,45 and it is basic.

Explanation:

The pH is a measure that gives us an idea of the acidity or alkalinity of a solution. It is calculated as:

pH = -log (H +)= -log (0.0000000035)=8, 46

The pH scale ranges from values of 0 to 14 (less than 7.0 is acidic and greater than 7.0 is basic, a pH = 7.0 is neutral).

In this case, the solution is basic (value greater than 7.0 ).
