|
|
In neutralisation reactions between an acid and an alkali, hydrogen ions react with hydroxide ions to produce water. |
|

The pH scale, from 0 to 14, is a measure of the acidity or alkalinity of a solution, and can be measured using universal indicator or a pH probe. |
|
What piece of digital equipment can be used to measure the pH of a solution? |
|
|
|
A solution with pH 7 is neutral. Aqueous solutions of acids have pH values of less than 7 and aqueous solutions of alkalis have pH values greater than 7. |
|
What pH values do each of acidic, alkaline and neutral solutions have? Define the following terms:
• acid
• base
• alkali
• neutral.
Recall the pH numbers for the following solutions:
• acidic
• alkaline
• neutral.
Write the symbol equation for the neutralisation of an acid and an alkali.
