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:

option - B is correct .....,.............

Answer 2

Answer:

To test the chemical properties of the product formed after adding metallic ash in water and observing a change in color, the student should perform a suitable chemical test.

Out of the given options, the most appropriate test to perform would be to test the basicity using a red litmus paper. The reason for this is that the change in color of the solution indicates that a chemical reaction has occurred, which may have resulted in the formation of a base. The red litmus paper will turn blue in the presence of a base, confirming the basic nature of the product formed.

Evaporating the solution to get crystals may help identify the compound formed, but it will not test its chemical properties. Testing the acidity using a blue litmus paper is unlikely to be useful since the change in color indicates that the product is more likely to be basic than acidic. Measuring the temperature change using a thermometer may indicate whether the reaction was exothermic or endothermic, but it will not provide information about the chemical properties of the product.
