Question

A student adds some metallic ash in water taken in a test tube. The ash gets

completely dissolved in water and the solution changes colour. What should

the student do next to test the chemical properties of the product formed?


(a) Evaporate the solution to get crystals.

(b) Test the basicity using a red litmus paper.

(c) Test the acidity using a blue litmus paper.

(d) Measure the temperature change using a thermometer.​

Answer 1

Answer:

i think answer would be frist one

Answer 2

(b) Test the basicity using a red litmus paper will be the next to test the chemical properties of the product formed.

Explanation:

• Metallic ash (Metal oxide) is a chemical compound which is formed when a metal is heated with oxygen.
• Metal oxides are solids (crystalline solids).
• A metal cation and an oxide anion are the major components of a metal oxide.
• When a metal oxide reacts with water, a base will be formed.
• Hence here, the basicity of the solution using a red litmus paper should be done to find out the chemical properties of the product formed.
