Step 1
What is the consequence of having large concentrations of Mg²⁺ and Ca²⁺ ions in waterways?
Answer
The large concentrations of Mg²⁺ and Ca²⁺ ions in waterways primarily lead to increased water hardness. Hardness refers to the concentration of divalent metal ions, such as Ca²⁺ and Mg²⁺, which can affect water quality and aquatic life. This condition can influence the biological processes in the water, such as nutrient absorption and the overall ecosystem health.
