Question

a correct way of preparing dilute acid using water is
a) adding water to acid. b) adding acid to water. c) mixing acid and water simultaneously. d) adding water to acid in a shallow container
​

Answer 1

Answer:

So much heat is released that the solution may boil very violently, splashing concentrated acid out of the container and all this because the reaction is exothermic. ... So it is always safer to add acid to water, and not water to acid. plz mark me Brainliest

Answer 2

The correct answer is option (b) Adding acid to water.

• While preparing a dilute solution of acid we should slowly add acid to water.
• Since all acids have a high affinity towards water, Adding water to acid will lead to a highly exothermic reaction.
• This can cause explosions and chemical burns.
• This also implies that the mixing of acid and water should be done in a deep container.
• The volume of water taken should be large enough to absorb heat evolved from the reaction.
• The water-acid solution should be simultaneously stirred While mixing acid with water this also helps to dissipate heat and avoids the concentration of acid at one point in the container.

Hence, while preparing a dilute solution of acid, Acid should be added to water slowly with constant stirring.
