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.
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
