1. Successive deprotonations -------------- the () charge density on the resulting anion.
2.This results in unfavorable electrostatic --------- between the carboxylate anions, which reduces the likelihood that a proton would ----------
3.it is more favorable for the proton to remain bound to reduce unfavorable charge----------- . .
Explanation / Answer
1. Successive deprotonation increase the (-) charge density on resulting anion.
2. This results in unfavourable electrostatic repulsions between the carboxylate anion which reduce the likelihood that a proton would dissociate.
3. It is more favourable for proton to remain bound to reduce unfavourable charge repulsions.
