Answer the following question: Answer the following question given this paragraph: Molten Salts and Ionic Liquids Heating a salt to its melting point produces a molten salt. If we heated a sample of solid NaCl to its melting point of 801C, for example, it would melt to give a stable liquid that conducts electricity. The characteristics of molten salts other than electrical conductivity are their high heat capacity, ability to attain very high temperatures (over 700C) as a liquid, and utility as solvents because of their relatively low toxicity. Molten salts have many uses in industry and the laboratory. For example, in solar power towers in the desert of California, mirrors collect and focus sunlight to melt a mixture of sodium nitrite and sodium nitrate. The heat stored in the molten salt is used to produce steam that drives a steam turbine and a generator, thereby producing electricity from the sun for southern California. Due to their low toxicity and high thermal efficiency, molten salts have also been used in nuclear reactors to enable operation at temperatures greater than 750C. One prototype reactor tested in the 1950s used a fuel and a coolant consisting of molten fluoride salts, including NaF, ZrF 4, and UF4. Molten salts are also. Q: Ionic liquids heating a salt to its melting point produces a what? Choices: - table salt - plasma - gas - molten salt A:
