Acid Base Balance

Question 1

Neutral

Answer 1

A solution with a pH of seven; the solution contains equal numbers of hydrogen ions and hydroxide ions

Question 2

Acidic

Answer 2

A solution with a pH below seven; in this solution, hydrogen ions predominate

Question 3

Basic or alkaline

Answer 3

A solution with a pH above seven; in this solution, hydroxide ions predominate

Question 4

Acid

Answer 4

A substance that dissociates to release hydrogen ions, decreasing pH

Question 5

Base

Answer 5

A substance that dissociates to release hydroxide ions or to tie up hydrogen ions, increasing pH

Question 6

Salt

Answer 6

And ionic compound consisting of a cation other than hydrogen and an anion other than a hydroxide ion

Question 7

Buffer

Answer 7

A substance that tends to oppose changes in the pH of a solution by removing or replacing hydrogen ions; in body fluids, buffers maintain blood pH within normal limits

Question 8

Strong acids and strong bases

Answer 8

Dissociate completely in solution. For example, hydrochloric acid, a strong acid, dissociates in a solution by the reaction HCL➡️H+Cl

Question 9

Carbonic acid is a weak acid. At the normal pH of the ECF and equilibrium exists and the reaction is

Answer 9

H2CO3 ↔️ H + HCO3
