Answer:
0.032 M
Explanation:
pH denotes the acidity or alkalinity of an aqueous solution. pH stands for potential hydrogen. The letter “p” denotes potential and the letter “H” denotes for hydrogen. A pH number varies from 0 to 14 depending upon on how acidic or alkaline a liquid is. Any aqueous solution that has pH above 7 is alkaline and any aqueous solution that has pH below 7 is acidic.
ph of phosphoric acid = 1.5
pH = -log[[tex]H_3O^+[/tex]]
1.5 = -log[[tex]H_3O^+[/tex]]
-1.5 = log[[tex]H_3O^+[/tex]]
[tex][H_3O^+]=10^{-1.5}[/tex] = 0.032 M
