A normal $\mathrm{KCl}$ solution contains $175 \mathrm{mEq} / \mathrm{L}$ each of $\mathrm{K}^{+}$ and $\mathrm{Cl}^{-} .$ How many moles each of $\mathrm{K}^{+}$ and $\mathrm{Cl}^{-}$ are in $2.00 \mathrm{~L}$ of the $\mathrm{KCl}$ solution?

Key Concepts

Milliequivalents and Equivalents

Milliequivalents (mEq) are a unit that expresses the chemical activity of ions in a solution, reflecting the amount of a substance that reacts with or supplies one mole of charge. For monovalent ions, where each ion carries a charge of one, 1 mole is equivalent to 1000 mEq. This relationship is crucial for converting between mEq and moles in solution concentration problems.

Mole Concept and Stoichiometry

The mole is a fundamental unit in chemistry that measures the amount of substance. In stoichiometric calculations, the relation between moles and other units like equivalents or milliequivalents is essential, especially when dealing with ionic compounds. The stoichiometric balance in a compound like KCl allows for direct conversion between the moles of the compound and the individual ions present, assuming a 1:1 ratio.

Solution Concentration and Volume Relationship

Understanding the relationship between the concentration of a solution (expressed in units such as mEq/L) and the volume of the solution is critical for quantifying the total amount of substance present. By multiplying the given concentration by the volume of the solution, one can determine the overall moles or equivalents of the ion or compound present in the solution.
