No.
An acid will dissolve something faster.
Generally not. The general rule to go by is like dissolves like. Polar substance will dissolve other polar substances while nonpolar substances will dissolve other nonpolar substances.
Unlike salt and sugar, petrol is a nonpolar substance, meaning that the electrons in its molecules are evenly distributed, rather than concentrated in some areas to make the molecule negatively charged on one side and positively charged on the other, as is the case with polar substances. Polar substances, as well as ionic substances such as salt, tend to dissolve more effectively in other polar substances, such as water, while nonpolar substances tend to dissolve well in nonpolar substances, such as oil. So while salt and sugar dissolve well in water, and oil might dissolve well in petrol, salt and sugar will not dissolve to any great degree in petrol.
The warmth make the molecules of some substances move faster.
slower
Ionic compounds
All substances are dissolved faster at high temperature.
You can make a solute dissolve faster by mixing the solute, heating the solute, or crushing the solute.
substance dissolve faster in a solvent? A catalyst can make a substance dissolve faster in a solvent. Increase temperature.
Substances that do not dissolve are insolubles, because they are not soluble they do not dissolve.
using hot water will dissolve it.
Heat it
