Conductivity indicates what in water?

• A. pH level
• B. Dissolved salts and minerals as ions
• C. Dissolved oxygen
• D. Turbidity

Answer: (B)

Electrical conductivity indicates how readily electricity passes through water, which depends on the presence of dissolved ions. When salts and minerals dissolve, they form ions that move and carry charge. The more dissolved ions present, the higher the conductivity. Pure water has very few ions and thus low conductivity. This measure is not a direct readout of pH, dissolved oxygen, or turbidity—pH reflects acidity/basicity, dissolved oxygen is the amount of oxygen gas dissolved, and turbidity relates to suspended particles affecting clarity. So, conductivity mainly reflects the concentration of dissolved salts and minerals as ions.
