Question

The equation for the ph of a substance is ph = –log[h+], where h+ is the concentration of hydrogen ions. What is the approximate ph of a solution if the concentration of hydrogen ions is 5. 0 × 10–4 moles per liter? 2. 7 3. 0 3. 3 3. 6.

Answer 1

The pH of the substance is 3.3 which is acidic.

What is pH?

The pH of a substance or solution is referred to the degree of acidity or alkalinity of that substance. It is measured on a scale of 0 -14.

• pH <7 are termed acidic

• pH >7 are alkaline

• pH =7 are termed neutral

Given  the concentration of hydrogen ions as 5. 0 × 10–4 moles per liter,we  use the formulae

ph = –log[h+]

plugging in thge value of  h+ as 5. 0 × 10–4 moles per liter we have:

pH = –log{5. 0 × 10–4 ]

pH=3.3
