Question

What is the total molar concentration of ions in each of the following solutions?

A) A 1.250 M solution of CH3OH
B) A 0.225 M solution of HClO4
A.5.500 M, 0.450 M
B.2.675 M, 0.1125 M
C.6.250 M, 0.225 M
D.3.125 M, 0.1125 M

Answer 1

The total molar concentration of ions in a 1.250 M solution of CH3OH is 0 M. The total molar concentration of ions in a 0.225 M solution of HClO4 is 0.225 M for H+ ions and 0.225 M for ClO4- ions.

Step-by-step explanation:

The molar concentration of ions in a solution is determined by the molar concentration of the solute. In this case, the solutes are CH3OH and HClO4. To find the total molar concentration of ions in each solution, we need to determine the number of ions produced by each solute.

A) CH3OH does not dissociate into ions in solution, so there are no ions present. Therefore, the total molar concentration of ions in a 1.250 M solution of CH3OH is 0 M.

B) HClO4 dissociates into H+ and ClO4- ions in solution. Therefore, the total molar concentration of ions in a 0.225 M solution of HClO4 is 0.225 M for H+ ions and 0.225 M for ClO4- ions.
