Mixing Dissolving

                                 Mixing + Dissolving  

what is a mixture.

A mixture is a substance made by combining two or more different materials in such a way chemical reaction occurs. A mixture can usually separated back into its original components.

Question

What factors affect dissolving?

solubility is the maximum amount of a substance that will dissolving in a given amount of solvent a specific temperature. there are two direct factors that affect solubility of both solids and gases, but pressure only affects the solubility of gases.

 

Method 

1. 50ml cold water + 1 spatula sugar = mixed 

2. 50ml hot water + 1 spatular sugar = stirred 

3. 50ml not water + 1 spatular sugar = no stirred 

3 50ml cold water + 1 spatular sugar = no stirred

conclusion

when your stir a spoonful of sugar into a glass of water, your are forming a solution. this type of liquid solution is composed of a solid solute, which is the sugar, and a liquid solvent, which is the water. As the sugar molecules spread evenly throughout the water, the sugar dissolving.
