0.203 is the mean of the concentration of the HCl solution

Explanation:

You have 5 concentrations. The most appropiate result is the mean of those results. The mean is a statistical defined as the sum of each result divided by the total amount of results. For the results of the problem, the mean is:

0.210 + 0.204 + 0.201 + 0.202 + 0.197 = 1.014 / 5 =

harkovskaia [24]

An ionic compound that results from the reaction of an acid and a base is called a(n) salt. the cation in this compound comes from the base while the anion comes from the acid.

When an acid and a base are together, they react to counteract each other's effects and create a salt.

Water is created when the OH(-) anion of the base and the H(+) cation of the acid mix.

A salt is a substance that is created when an anion from an acid and a base combine.

Common table salt, NaCl, is created when sodium hydroxide and hydrochloric acid are combined.

The positive ion (cation) of a base and the negative ion (anion) of an acid make up a salt.

A neutralizing reaction occurs when an acid and a base interact. Additionally, sodium chloride, generally known as table salt, is referred to as salt.
