When an acid or alkali substance is turned neutral.

2

What chemical equation is used to show he making of salt?

Base + Acid = Salt + Water

B + A = S + H2O

BASHO

4

What is BASHO?

Base (alkali) + Acid = Salt + H2O (water)

It is a neutralisation reaction

5

What happens when you mix an acid and an alkali?

Depending on how balanced the strength of the acid and alkali is, if they are roughly the same strength they should neutralise each other.

7

What two things can you use to measure the PH of a liquid?

Universal indicator {doesn't work with anything but liquid}

Litmus Paper {works with things other than liquid}

8

What are Antacids?

Antacids are pills or powers that people eat to reduce stomach acid. They contain alkali to neutralise the acid.

On a PH scale, what colour is an acid?

Red, orange and yellow

12

On a PH scale, what colour is an Alkali?

13

On a PH scale, what colour is Neutral?
