A solution is prepared by mixing 0.10 of 0.12 M sodium chloride with 0.23 L of a 0.18 M magnesium chloride solution. What is the pCl- of the resulting solution?

pCl⁻ = 0.54

Explanation:

First we calculate how many Cl⁻ moles are coming from each substance, using the given volumes and concentrations:

The final volume of the mixture is = 0.10 L + 0.23 L = 0.33 L

Now we calculate [Cl⁻], using the total number of Cl⁻ moles and the final volume:

Finally we calculate the pCl⁻ of the resulting solution:

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
