it is possible to make a buffer that functions well near pH 7 using citric acid, which contains only carboxylate groups. Explain. Drag the terms on the left to the appropriate blanks on the right to complete the sentences.

Words : decrease, increase, repulsion, associates, attractions, dissociate

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----------- . .

Answer:

1

Successive deprotonations increase the (−) charge density on the resulting anion.

2

This results in unfavorable electrostatic repulsion between the carboxylate anions, which reduces the likelihood that a proton would dissociate

3

It is more favorable for the proton to remain bound to reduce unfavorable charge repulsion

Explanation:

Generally

Successive deprotonations decrease the (−) charge density on the resulting anion.

This because deprotonations means removal of positive charge

This results in unfavorable electrostatic repulsion between the carboxylate anions, which reduces the likelihood that a proton would dissociate

It is more favorable for the proton to remain bound to reduce unfavorable charge repulsion
