Answers
Answer:
A) Milk in water- No effect
B) Baking powder in water- turns blue
C) Vinegar in water- remains red
D) Glucose in water- no effect
Explanation:
Litmus paper is used to determine whether a given solution is acidic or alkaline.
A red litmus paper turns blue if solution is alkaline.
A blue litmus paper turns red if solution is acidic.
Milk & Glucose does not affect the Litmus paper as they are neither acidic nor alkaline.
Baking powder solution is alkaline so the colour of the red litmus paper turns blue.
Vinegar solution is acidic so it does not result in colour change and remains red.
