Note: Make sure you have adult supervision it you burn a candle or melt butter or chocolate. Site Search. Science Facts. What is the difference between melting and dissolving? Materials you will need:. Subjects :. Students should make some comparison about how this process has been different from their observation of melting above.
Students can then dissolve substances in solvents other than water, such as eucalyptus oil and acetone nail polish remover. This can be linked to the use of cleaning products around the house, which are designed to dissolve fats and oils. In order to consider the reverse of dissolving, pour small amounts of concentrated solutions like copper sulphate, salty water or shellac in methylated spirits into saucers and leave to evaporate.
Students can observe the changes over time. Using the technique of Predict-Observe-Explain ask students to predict what will happen to the weight of the water when sugar is dissolved. Record changes in weight when sugar is added to water and stirred to dissolve. You can show that the resulting solution has the same weight as the sugar and water separately. In order to consider the reverse of dissolving, students could undertake a research project to find out how table salt is commercially produced.
This will help them to identify some of the differences between melting and dissolving. Some other projects student could explore include glass blowing and the production of silver jewellery.

An example is a coffee powder solid solute and hot water solvent. When the coffee powder is mixed in the hot water, it forms a solution the coffee drink. It is very simple to understand the difference of the two concepts in the examples given.
Melting and dissolution are two processes that can be used in chemical industries and mining. Dissolution is often used among gold compounds. Melting, on the other hand, is used more in cooking such as the melting of butter, melting a bar of chocolate, and so on and so forth.
These two concepts are specifically discussed in chemistry. The rate of dissolution and melting depends on the compound and the chemical properties of the solute and solvent for dissolving. Melting is also called fusion while dissolving is also called dissolution. Melting involves a change of the physical state from a solid to a liquid without the use of a solute or solvent while dissolving involves the use of a solute and solvent to produce a solution.
