Question

a solution turns red litmus blue its ph value would be a/NaCl soution and copper b/MgCl2 solution and aluminum c/FeS04 solution and silver metal d/AgNO3 solution and copper metal​

Answer 1

Answer:

d)

Explanation:

Answer 2

A solution turns red litmus blue its ph value would be

d/ AgNO3 solution and copper metal

1. Copper is place higher in the reactivity series than silver.

2. Hence it displaces silver from silver nitrate

3. As a result copper (II) nitrate is formed.

4. Cu2+ is acidic since it is a transition metal, and NO3- being neutral, the result is the base of a strong acid, that is acidic.

5. This turns red litmus blue.

6. It's pH is 3.70.
