Ph Scale

The pH scale measures

• the acidity of a chemical
• the reactivity of a chemical
• the boiling point of a chemical
• the electrical conductivity of a chemical

The pH measures between 

• 0 and 10
• 0 and 7
• 7 and 14
• 0 and 14

The pH of all acids will be between:

• 0 - 14
• 0 - 7
• 5 - 10
• 7 - 14

The pH of all alkalis (soluble bases) will be between:

• 0 - 14
• 0 - 7
• 5 - 10
• 7 - 14

The pH of a strong acid would be:

• 1-2
• 5-6
• 8-9
• 12-13

The pH of a strong base would be:

• 1-2
• 5-6
• 8-9
• 12-13

The pH of a weak base would be:

• 1-2
• 5-6
• 8-9
• 12-13

The pH of a weak acid would be:

• 1-2
• 5-6
• 8-9
• 12-13
