We're being asked to determine which among the given statements are correct given that:
Formic acid is a weak acid and hydrochloric acid is a strong acid.
Weak acids are weak electrolytes that don’t completely ionize but instead reach a state of equilibrium.
Strong acids are considered strong electrolytes. They completely dissociate into ions when dissolved in water.
Let's take a look at each statement given:
Formic acid is a weak acid and hydrochloric acid is a strong acid. It follows that the:
This question has multiple correct options
a. [OH-] of 0.01 M HCl(aq) will be less than that of 0.01 M HCOOH(aq)
b. solution containing 0.1 M NaOH(aq) and 0.1 M HCOONa(aq) is a buffer solution
c. pH of 10-9 M HCl(aq) will be approximately 7 at 25°C
d. pH of a solution formed by mixing equimolar quantities of HCOOH and HCl will be less than that of a similar solution formed from HCOOH and HCOONa
