Continuation of Acids and Alkali Worksheet

Headline: Continuation of Acids and Alkali Worksheet.

In today's Science lesson, we went through the worksheet on acids and alkalis which we had gone through part of it yesterday.

I learnt that:

• In car engines, it is very unlikely for the measurement of pH to be done
• The acid in car battery is very acidic, which have a pH of 1
• Distilled water is neutral with a pH of 7
• The alkali in potassium hydroxide is very alkaline as it has a pH of 13
• When the universal indicator is added to an acid, the colour of it will first be green, then change to yellow, then orange and then red
• As for when the universal indicator is added to a very strong alkali, with a pH of 14, it will turn violet in colour
