Hi, someone please help me with this and how am i gonna know if it's acidic or basic?

Question

Calculate the

hydrogen ion

concentration of a

solution with a pOH

reading of 7.8

Answer 1

If the pH is greater than 7, it is basic. If the pH is less than 7, it is acidid.

pOH = 7.8

pH + pOH = 14

Solving for pH we have pH = 14 - pOH = 14 - 7.8

pH = 6.2 (acidic)
