^{Explain why water is known as universal solvent?}

Why water + starch shows Tyndall effect explain?

Answer 1

1)

• Suspensions are used in medicine to administer an insoluble compound as a liquid
• It is also used to mask the unpleasant taste of a drug

2) If we use hot water, The colloid will get coagulated due to the high temperature .

3)Water is capable of dissolving a variety of different substances, which is why it is such a good solvent. And, water is called the "universal solvent" because it dissolves more substances than any other liquid. This is important to every living thing on earth

4)Startch solution is a colloid and contains starch particles/ molecules. These molecules are large enough to disperse light and hence they show tyndall effect.
