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.

n has four pairs of electrons in the valence shell, electrons repel one another ,n has 7 protons in its nucleus, and since n has 7 protons, it must fill the second shell, giving it 4 pairs of electrons. the electrons form 3 bonds and 1 lone pair of electrons. each pair of electrons repels the other pairs, so they are equally far apart.

so all of the above

i think it is true since you can test the answer and can use observations to complete it.
