You have probably learned that water freezes into ice when the temperature reaches the freezing point: 32 degrees Fahrenheit (which is the same as 0 degrees Celsius).This is true for pure water, but adding things like salt or sugar can lower the freezing point. Just below 32F, ice in pure water will stay frozen, but ice in salt water will melt. This is why people who live in cold places put salt on the roads. The salt lowers the freezing point, so even at temperatures below 32F, water will stay a liquid instead of freezing into slippery ice.

Sugar has the same effect, but it is not as dramatic as with salt. A general answer to your question is, water with “stuff” dissolved in it will usually melt ice faster than pure water. If there are particular liquids you are curious about (like soda, juice, milk, salty water, or soapy water), you could try doing an experiment yourself! Put an ice cube in a glass of each liquid, and time how long it takes them to melt. Of course, there are a lot of other factors that affect the melting time: starting temperature of the liquid, density, whether it is stirred… and so on.
