An acid is a substance that donates protons.

true or false answer !

The correct answer is True.

Explanation:

An acid is a molecule that has the property of donating a proton or accepting a pair of electrons during a reaction.

The strength of an acid is related to their tendency to lose a proton. A strong acid is one that separates all its components when it comes into contact with water.

As its composition includes hydrogen ions, the more its concentration, the higher the acidity will be, and the lower the pH of the solution.

Its main characteristic is that on contact with water they produce a sour taste.

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
