Complete Question
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
Step-by-step 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
