1

what is ionization?

ionization is the process of forming ions
- the reaction can go in either direction

2

What happens during the ionization of water?

- a hydrogen breaks away and becomes a positively charged hydrogen ion that combines with water to form a hydronium ion
- the hydrogen ion remaining in the OH group shares an electron with an oxygen forming a negatively charged hydroxide ion

3

What are acids?

acids produce hydrogen and hydronium ions in water-based solutions and have a positive charge

4

What are bases?

bases produce hydroxide ions in water based solutions and have a negative charge

5

What are neutral substances?

acids and bases form a compound with ionic bonds, called Salts
- neutral substances have a balance of positive and negative substances

6

How do bases feel?

bases feel slippery

7

How do bases taste?

bases have a bitter taste

8

what do acids taste like?

acids have a sour taste

9

What are organic dyes?

are colour pigments that change colour with the presence of acids or bases
-bases tun litmus paper blue and acids turn it red

10

Like organic dyes acids and bases do what?

acids and bases affect fruits and vegetables like organic dyes
- green vegetables turn brighter in when a base is added during cooking

11

What is a pH Scale?

expressed the degree of c
