Answer 1

Answer:

When an acid and a base are placed together, they react to neutralize the acid and base properties, producing a salt. The H(+) cation of the acid combines with the OH(-) anion of the base to form water. The compound formed by the cation of the base and the anion of the acid is called a salt.

What do you mean by indigestion?

$\green{\underline{\boxed{\odot\mid{\bf{Answer:-}}}}}$

Indigestion — also called dyspepsia or an upset stomach — is a general term that describes discomfort in your upper abdomen. Indigestion is not a disease, but rather some symptoms you experience, including abdominal pain and a feeling of fullness soon after you start eating.
