Question

A milkman adds a very small amount of baking soda to fresh milk what happens to its ph

Answer 1

Nothing happens because milk is slight acid so when base react it remains the same

Answer 2

When milkman adds baking soda to milk then the acids present in milk which turn the milk into curd are neutralised by baking soda. It means that the milk becomes basic. As the milk becomes basic so it means that it's ph is increased.

Because we know that higher the hydronium ion concentration lower the ph. Here, hydronium ion concentration has been reduced so ph will increase.
