b.  An antacid tablet is taken when you suffer from acidity.

Sandy soil is not used for making pots.    ​

Answer 1

Answer:

Explanation:

(A): We should water the plants before sunrise and after sunset because water get evaporated more quickly in presence of sunlight . At this time the rate of evaporation of water is low and soil remain moist for a long time,-.

Acidity is caused due to the excess production of acids in the stomach. An antacid tablet contains bases, such as milk of magnesia(magnesium hydroxide, gelusil,etc. These bases react with excess of acids and neutralize the effect of excessive acid and brings relief.

Sandy soil consists of large particles that are loosely packed with large air spaces between them. In addition, it has a very poor water-holding capacity. As the particles are large and loosely packed, it is difficult to mould pots and lamps out of sandy soil.
