Correct answer: C. Hardnessकठोरता
Explanation
Hardness results from dissolved calcium and magnesium salts and is measured chemically, so it is a chemical parameter. Turbidity, temperature and colour are physical parameters of water quality. Answer: Hardness.कठोरता जल में घुले कैल्शियम और मैग्नीशियम लवणों के कारण होती है और रासायनिक रूप से मापी जाती है, अतः यह रासायनिक मापदंड है। आविलता, तापक्रम और रंग जल गुणवत्ता के भौतिक मापदंड हैं। उत्तर: कठोरता।More People, Development and Environment questions
