Murate of potash is chemically ________.
Verified Answer
A. Potassium hydrogen phosphate ($\text{K}_2\text{HPO}_4$)
B. Potassium nitrate ($\text{KNO}_3$)
C. Potassium sulphate ($\text{K}_2\text{SO}_4$)
D. Potassium Chloride ($\text{KCl}$)
Explanation:
Muriate of Potash (MOP) is the common name for the chemical compound Potassium Chloride, which has the chemical formula $\text{KCl}$. It is a widely used potassium fertilizer. Option A, Potassium hydrogen phosphate, also known as dipotassium phosphate, has the formula $\text{K}_2\text{HPO}_4$. Option B, Potassium nitrate, commonly known as saltpeter, has the formula $\text{KNO}_3$. Option C, Potassium sulphate, also known as Sulphate of Potash (SOP), has the formula $\text{K}_2\text{SO}_4$. Each of these compounds is a source of potassium, but only Potassium Chloride is referred to as Muriate of Potash. Therefore, the correct chemical name for Muriate of Potash is Potassium Chloride.
