1 M H2SO4 = 2 eq. of HCl Hence y = 2x or x = y/2

1. (a) y = 2x
2. (b) x = y/2
3. (c) x = y
4. (d) y = x

Correct answer: (b) x = y/2

Solution

1 M H2SO4 provides 2 equivalents of H+ ions, while 1 M HCl provides 1 equivalent of H+ ions. Thus, the relationship is x = y/2, where x is the molarity of HCl and y is the molarity of H2SO4.
