Acids & Bases

Question 0

Properties of a Base

Answer 0

Feel slippery
Taste bitter
Corrosive
Can conduct electricity (think alkaline batteries)
Do not react with metals
Turns red litmus paper blue

Question 1

Properties of a acid

Answer 1

Taste sour
Consists electricity
Corrosive, which means they break down certain substances
Some acids react strongly with metals
Turns blue litmus paper red

Question 2

What is a base

Answer 2

A base is a solution that has excess of OH- ions
Another name for a base is alkali
BASES are substances that can accept hydrogen ions

Question 3

What is an acid

Answer 3

An acid is a solution that has excess of H+ ions.

The more H+ ions! the more acidic the solution

Question 4

Acid reactions

Answer 4

Acid + Base = Salt + Water
Acid + Metal = Salt + Hydrogen
Acid + Carbonate = Salt + Water + Carbon Dioxide

Hydrochloric acids forms CHLORIDE salts
Nitric acids forms NITRATE salts
Sulfuric acid forms SULFATE salts

Question 5

Neutralisation Reaction

Answer 5

This is the equation for any neutralisation reaction

Acid + Base = Salt + Water

When an acid neutralises a base, the products are neutral (pH7)
