Question 16

Weak acid

Answer 16

acid that dissociates incompletely, releasing only some of its hydrogen atoms into the solution. less capable on donating protons. pH of less than 7

Question 17

Weak base

Answer 17

chemical base that does not ionize fully in an aqueous solution.
which protonation is incomplete. pH of greater than 7

Question 18

Concentrated

Answer 18

relatively large quantity of substance present in a unit amount of a mixture. More of solute dissolved in a given solvent.

Question 19

Dilute

Answer 19

the process of reducing the concentration of a solute in solution, usually simply by mixing with more solvent.

Question 20

Reaction of acid and base

Answer 20

React to neutralize the acid and base properties, producing a salt. H(+) cation combined with the OH(-) anion to form water. Compound formed by the cation of the base and the anion of the acid is salt

Question 21

Reaction with acid and metal

Answer 21

A salt, i.e. a combination of two ions, is formed; the particular salt formed depends on the acid used in the reaction is formed.

Question 22

Reaction with acid and carbonate

Answer 22

Salt is produced.

Question 23

Neutral

Answer 23

compound/ substance that is neither acidic nor alkaline
