4. The venom of biting ants contains formic acid, HCOOH (the H attached to the O is the acidic H). The Ka of formic acid is 1.80x10-4 at 25°C. a. Write the equation for the dissociation of the weak acid, formic acid. b. Give the Ka expression for formic acid. c. What is the equilibrium concentration of all species in a .625M solution of formic acid at 25°C?
