How to find the molar concentration of ions?
Understand the Problem
The question is asking for a method to calculate the molar concentration of ions in a solution. This typically involves knowing the amount of substance (in moles) and the volume of the solution (in liters). The formula used is (number of moles of solute) / (volume of solution in liters).
Answer
Multiply the molarity of the solute by the number of moles of ions produced per mole of solute.
To find the molar concentration of ions, multiply the molarity of the solute by the number of moles of each ion produced per mole of solute.
Answer for screen readers
To find the molar concentration of ions, multiply the molarity of the solute by the number of moles of each ion produced per mole of solute.
More Information
When a solute dissolves in water, it dissociates into its constituent ions. By knowing the initial molarity of the solute and its dissociation ratio, you can calculate the molarity of each ion.
Tips
Do not forget to account for all the ions produced. For instance, Na2SO4 dissociates into 2 Na+ and 1 SO4^2-, so the ion concentrations will differ.
