Molecular and Ionic Equations | Chemistry for Non-Majors
Molecular and Ionic Equations When ionic compounds are dissolved into water, the polar water molecules break apart the solid crystal lattice, resulting in the hydrated ions being evenly distributed through the water. This process is called dissociation and is the
Lab 10 - Solubility Product for Calcium Hydroxide
The concentration of Ca(OH) 2 (s) does not appear in the equilibrium constant expression because it is always present as the pure solid (activity is 1), no matter how much or how little of it is present. A saturated solution of Ca(OH) 2 can be prepared by the reaction of calcium metal with water.

Difference Between Sulphuric Acid and Hydrochloric …
2011/10/13· Sulphuric Acid vs Hydrochloric Acid We normally identify an acid as a proton donor. Acids have a sour taste. Lime juice and vinegar are two acids we come across at our homes. They react with bases producing water, and they react with metals to form H 2; thus, increase metal corrosion rate.
