Correct answer
B1.78

Step-by-step explanation

pH of a mixture of HCl+H2SO4 has to calculated

The number of equivalents of HCl is equal to 0.02 equivalents

The number of equivalents of H2SO4 given is equal to 0.008 equivalents

Hydrogen ion concentration of the resultant mixture is equal toH+=0.01×200+0.01×2×400600

=2+8600=10600=160

pH=-log160

=1.78
