The amount of sodium phosphate in treated boiler water can be measured by a/an _______________.
AI Explanation
The correct answer is D) phosphate test.
The amount of sodium phosphate in treated boiler water can be measured by a phosphate test. Sodium phosphate is added to boiler water as a water treatment chemical to prevent scale formation and corrosion. A phosphate test is the appropriate method to directly measure the concentration of phosphate ions in the water, which indicates the amount of sodium phosphate present.
The other answer choices are incorrect because an alkalinity test measures the buffering capacity of the water, a chloride test measures the chloride ion concentration, and there is no such thing as a "sodium phosphorous test" for boiler water analysis.
