Station 4 : Who Am I?

My Observations Substance

Colour in change of litmus paper

Chemical property

A (Lime juice) Blue to red Acidic B (Liquid soap) Red to blue Alkaline C (Sugar solution) No changes Neutral D (Detergent) Red to blue Alkaline E (Vinegar) Blue to red Acidic F (Plain water) No changes Neutral (12 markah)

My Conclusions d) Substances A and E are acidic

e) Substances B and D are alkaline

f) Substances C and F are neutral (3 marks)

Questions 2) Substance X turns blue litmus paper to red. What is the taste of X?

Sour (1 mark)

2) Give a reason of this statement.

Toothpaste will turn red litmus paper to blue (1 mark)
