Study Notes
Acids, Bases, and Neutrals
- Acids turn litmus paper red
- Bases turn litmus paper blue
- Neutrals do not change litmus paper color
- Acids have a sour taste
- Bases have a bitter taste
- Bases feel slippery
Physical vs. Chemical Changes
-
Boiling water is a physical change because the water molecules are not rearranged and the original substance is present, just in a different state
-
Adding sugar to water and making it dissolve is a physical change because the sugar molecules are dispersed in the water, but the original substances are still present, just different states
-
Neutralization is a chemical change, it forms a new substance
-
Folding paper or cooking an apple pie are physical changes
-
Cooking an apple pie is a chemical change
Solubility
- Solubility is the ability of a substance to dissolve in another substance
- As temperature increases, the solubility of most substances increases
- The substances in this graph which are being dissolved into water are Potassium Nitrate, Sodium Chlorate, and Sodium Chloride
- Materials in solution are more soluble in higher temperatures
