Question

How many grams of HCl are needed to make 250. mL of a strong acid solution having a pH equal to 1.00

Answer 1

Answer #1

pH =1 , so that [H+] = 0.1

Conc. =weight *1000/mol.wt* volume

0.1=weight*1000/36.5*250

Weight =0.1*36.5*250/1000

Weight = 3.65/4

Weight =0.9125 grams

Mol. Wt of HCl=36.5
