Precipitate chemical reaction

One of the signs of a chemical reaction is the formation of a precipitate. When two liquids react and the product is a solid, it is called a precipitate. The precipitate forms because the solid (AgCl) is insoluble in water. That is true for all precipitates – the solids are insoluble in aqueous solutions. Precipitation reaction occur all around us.

Precipitation reactions occur when cations and anions in aqueous solution combine to form an insoluble ionic solid called a precipitate. Whether or not such a reaction occurs can be determined by using the solubility rules for common ionic solids. Because not all aqueous reactions form precipitates, one must consult the solubility rules before determining the state of the products and writing a net ionic equation.

The 1970's was the decade that illuminated the threat of acid rain to the citizens of the US. It had been known to exist several years before, but the sources of the problem did their best to suppress...

PRECIPITATION: LEAD IODIDE (2 of 2) Reaction of Potassium Iodide with Lead Nitrate As the 0.1M clear solution of Pb(NO3)2 in the pipette is poured into the 0.1M clear solution of KI (potassium iodide) in the Erlenmeyer flask, a yellow precipitate of PbI2 (lead iodide) is formed.

Chemical reaction in science today :) @vindictivemoron

Science is beautiful.

Here's Part 1 of the chemical reactions posters, including precipitation, decomposition, combustion, addition and neutralisation. Further parts to come, so don't worry if there's a reaction not yet...
