Does vinegar water freeze faster than water?

Answer 1

According to my experiments, ice melts faster in water than in vinegar. It takes roughly twice as long to melt in vinegar than water when both the vinegar and water are at room temperature. I think the reason is vinegar is slightly more dense than water and what happens is as the ice melts in vinegar it forms a cool layer of water in the surface. The ice floats so it's in contact with the cool layer. When ice is in water, as the ice melts, the melted water is cooler an denser and drops to the bottom, so the ice floating in water is always in contact with a warmer layer of water.

Answer 2

No, vinegar water does not freeze faster than plain water. In fact, adding vinegar to water can lower its freezing point slightly, but this effect is minimal and would not lead to the vinegar water freezing faster than plain water.

Answer 3

"Freeze faster" is hard to quantify.

A solution of acetic acid in water (i.e. vinegar) freezes at a lower temperature than pure water does, if that's what you mean, but I think you'd probably call that freezing slower, not faster.

Answer 4

Vinegar, because it is a gas and will let out oxygen while it is melting.

Answer 5

vinegar, because it is acidic and therefore has a higher concentration of ions

Answer 6

Colligative properties. Specifically, freezing point depression. Almost everything freezes at a lower temperature when it's impure than when it's pure.

Answer 7

it melt faster with salt

Answer 8

unknown.

Answer 9

vinegar

Answer 10

Salt
