Appearance: White solid, hygroscopic White hygroscopic powder 50 mL of each sample solutions, which were put in glass tube right after the completion of magnetic exposure to obtain the conductivity of solution.This is an example of a double displacement reaction. There are many other factors that can affect solubility, but these rules are a good first step. We will then compare our actual yield to the theoretical yield to compute our percent yield for our experiment according to the following balanced chemical equation. The finished reaction is: 2 KCl (aq) + Pb (NO 3) 2 (aq) 2 KNO 3 (aq) + PbCl 2 (s) The solubility rules are a useful guideline to predict whether a compound will dissolve or form a precipitate. We will separate and dry this precipitate to measure our actual yield. show more Sodium carbonate (anhydrous), Na2CO3, Disodium carbonate, Natriumkarbonat, Carbonic acid sodium salt (1:2), Anhydrous sodium carbonate, Carbonic acid, disodium salt, Sodium carbonate, anhydrous, Soda-ash, Natrum carbonicum, Sodium carbonate anhydrous, Sodium salt of carbonic acid, Carbonic acid disodium salt show less Calcium carbonate precipitate is formed as a result: CaCl2 + Na2CO3 -> CaCO3 + NaCl. This means PbCl 2 is insoluble and form a precipitate. Other names: Soda ash, Washing soda, Soda crystals.
