Candles contain paraffin wax, which is a white, odorless, tasteless, waxy solid, with a typical melting point between about 46 and 68 °C. Are candles pure or a mixture?
Question
Candles contain paraffin wax, which is a white, odorless, tasteless, waxy solid, with a typical melting point between about 46 and 68 °C. Are candles pure or a mixture?
Solution
Candles are considered a mixture rather than a pure substance. This is because they are made up of different components, not just paraffin wax. These components can include colors, fragrances, and sometimes other types of wax or additives. Each of these components has its own distinct properties, such as melting point, color, and smell. Therefore, because a candle is composed of multiple substances with different properties, it is classified as a mixture.
