Salt + H₂

Question 14

Acid + Oxide/Hydroxide Base

Answer 14

Salt + H₂O

Question 15

Acid + Carbonate/Hydrogen Carbonate Base

Answer 15

Salt + H₂O + CO₂

Question 16

Non-metal Oxide + H₂O

Answer 16

Acid

Question 17

Metal Oxide + H₂O

Hydroxide Base

Question 18

Titration

Answer 18

A laboratory technique used to determine the concentration of an unknown solution by reacting it with a solution of known concentration. During titration, a reagent (the titrant) is gradually added to the solution being tested (the analyte) until the reaction reaches its endpoint, which is usually indicated by a color change or by a change in some other measurable property, like pH.
