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:

chemical digestion occurs in the stomach were hcl and pepsin forms chyme, the mouth in which salivary amylase breaks down starch to form bolus, and the small intestine specifically the duodenum.
