The equation for the ph of a substance is ph = –log[h+], where h+ is the concentration of hydrogen ions. What is the approximate
Maru [420]

The pH of the substance is 3.3 which is acidic.

<h3>What is pH?</h3>

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
