Chapter 4 Solutions and Chemical Reactions
Types of Chemical Reactions and Solution Stoichiometry.
Electrolytes Some solutes can dissociate into ions. Electric charge can be carried.
Chapter 18 Ions in Aqueous Solutions Ionic Compounds in Aqueous Solution Theory of Ionization 1.Michael Faraday a. Atoms are associated with electrical.
Dissolving vs. Dissociating Sugar vs. Salt. Electrolytes: Charged particles or ions present in a solution can conduct an electric current. Ionic compounds.
Aqueous Reactions and Solution Stoichiometry. Aqueous Solutions Aqueous solutions are solutions in which water does the dissolving. –Solute – material.
Unit 8: Chemical Reactions Net Ionic Equations. Recall, aqueous (aq) means a substance that is dissolved in water.
Unit 3 – Chemical Reactions. In many ionic reactions, not all of the chemical species undergo a change. Those that do not change are called spectator.
Acidic, basic and neutral salts. Salts Salts are formed when acids react with bases. acid + base → salt + water When strong acids react with strong bases.
