Welcome back Ebube — missed you this week. Here are the answers to your chemistry questions: 1. Briefly describe the method of preparing soluble salt. Soluble salts can be prepared by reacting an acid with an excess of an insoluble reactant (like a metal, metal oxide, or metal carbonate), filtering off the unreacted solid, and then crystallizing the salt from the solution. Step 1: React a dilute acid with an excess of an insoluble base (e.g., metal oxide or carbonate) or a reactive metal. Step 2: Filter the mixture to remove any unreacted solid. Step 3: Heat the filtrate to evaporate some of the water, creating a concentrated solution. Step 4: Allow the concentrated solution to cool slowly, which causes the salt to crystallize. Step 5: Separate the crystals by filtration and dry them, for example, between filter papers. 2. State 3 examples of insoluble salt. Here are three examples of insoluble salts: Calcium carbonate* (CaCO_3) Barium sulfate* (BaSO_4) Silver chloride* (AgCl) 3. Name the following compounds: i) K_2CrO_4: Potassium Chromate* ii) Pb(NO_3)_2: Lead(II) Nitrate* iii) CaCO_3: Calcium Carbonate* iv) Na_2CO_3 · 10H_2O: Sodium Carbonate Decahydrate* v) FeSO_4 · 5H_2O: Iron(II) Sulfate Pentahydrate* Send me the next one 📸
