Toothpaste
Baking powder
Detergent

Question 3

Answer 3

Sodium hydroxide

Sodium bicarbonate

Question 4

What is an indicator

Answer 4

An indicator tells us whether a liquid is acidic or basic or neutral by means of colour change eg. Universal indicator paper/liquid

Question 5

What is the PH scale

Answer 5

The PH scale tells how acidic or basic a substance is (0-14)
7= neutral
8-14= basic
0-6= acidic

Question 6

What is neutralisation

Answer 6

Neutralisation is when an acid is added to a base until the solution is neutral (PH7

Question 7

What is titration

Answer 7

Titration allows us to measure exactly how much acid is required
Hydrochloride acid+sodium hydroxide -> sodium cholide + water
HCl + NaOH -> NaCl + H2O

Question 8

Acids reacting with metals

Answer 8

Zinc + hydrochloric acid -> zinc chloride + hydrogen gas
Zn + HCh -> ZnCl + H2o

Hydrogen gas burns with a pop
