Answer 2

The correct option is : C. A is true but R is false

Assertion: Fresh milk in which baking soda is added, takes a longer time to set as curd.

• When baking soda is added to milk, it increases the pH of the milk as it is alkaline in nature.
• Owing to this reason, the acid produced by bacteria for the curd formation is used up in neutralizing the alkalinity first.
• Due to this reason, milk in which baking soda is added, takes a longer time to set as curd.
• Thus, the assertion statement is true.

Reason: Baking soda decreases the pH value of fresh milk to below 6.

• Baking soda increases instead of decreasing the pH value of fresh milk as given here.
• Thus, the reason statement is not true.
