To increase the popularity of the chemical analysis section, a \"One Question per Day\" campaign has been launched to foster an active atmosphere for technical exchanges while offering members certain financial rewards. 【Daily Question】A molten sample is created by mixing the sample with ( ), and then heating it at high temperatures to convert the component of interest into a compound that is soluble in ( ) or ( ). Standard answer: solid flux, water, acid. Please reply with your answer; participating in this question earns +2 wealth points. Those who get all answers correct will receive an additional +3 to +8 wealth points. Those who provide a thorough analysis and explanation of the question or answer, or include detailed calculation processes, will receive extra wealth points as a reward. If your answer is correct and your analysis is accurate, it will be marked as the best reply (or best assistance). Feel free to answer the questions.
A molten sample is obtained by mixing the sample with a (solid flux) and heating it at high temperatures, thereby converting the component to be analyzed into compounds that are soluble in (water) or (acid).
