Chapter 17 Additional Aspects of Aqueous Equilibria

Chapter 17 Additional Aspects of Aqueous Equilibria . The Common Ion Effect. The common ion effect is an event that occurs when an ionic equilibrium shifts due to the addition of a solute that contains an ion that is the same as an existing ion in the equilibrium. .

Neutralization & Titration

Neutralization & Titration. Lynette Shao. Neutralization . Acids release H + ions into solutions and bases release OH - ions. Mixing the two solutions would cause H + and OH - to combine and make H 2 O (plain water). Neutralization will always produce water and salt. Example:

Solutions

Solutions. What is a solution?. Solution is a mixture of solute and solvent. Solute (normally solid) dissolves in solvent (liquid) to form the solution . In salt solution, salt is the solute and water is the solvent.
