IV.13. HYDROLYSIS (Hebden p. 144 – 148). Hydrolysis of a Salt Rx between water and cation &/or anion in salt that produces an acidic or basic solution.
An introduction to the properties of acids, bases, and the pH scale.
pH: a measure of the acidity or basicity of an aqueous solution The measure of hydrogen ions (these are positively charged)
pH: a mathematical measure of hydrogen ions and hydroxide groups in a solution.

Hands-On-Line Conclusion. Question 1 Which class would you choose? Explain why. Face-to-Face because I generally like to interact with other people.
Acids and Bases. Acids Acids are substances that release hydrogen ions, H +, in solution Acids are substances that release hydrogen ions, H +, in solution.
Noadswood Science, Sunday, October 12, 2014 To know how flame tests, the pH scale and solubility helps analytical scientists.
Salts and pH. Soluble salts dissociate in water to produce ions. Salts are basically ionic compounds that can be formed from the reaction from an acid.
Equations attempt to show only the exact particles involved in the reaction. Net Ionic Equations.
