When baking soda solution and calcium chloride solution are combined, a white precipitate of calcium carbonate forms due to a chemical reaction between the two compounds. This reaction also releases carbon dioxide gas, which may cause bubbling or fizzing in the solution.
If chloride is present silver chloride with get precipitated..
Blue litmus paper turning red indicates that the solution of ferric chloride is acidic. This is because ferric chloride is a strong acid, which will donate protons to the water molecules, increasing the concentration of H+ ions in the solution and lowering the pH.
When ethyne is passed through ammoniacal cuprous chloride solution, the blue color of the cuprous chloride solution fades as the ethyne reduces cuprous chloride to copper, forming reddish-brown copper. This reaction is a test for unsaturation in organic compounds.
Calcium carbonate and hydrochloric acid will react to produce calcium chloride, carbon dioxide gas, and water. When you observe the reaction, the solid calcium carbonate will disappear and gas bubbles will form. This is because the solid calcium carbonate reacts with the hydrochloric acid to form soluble calcium chloride, carbon dioxide gas, and water. The balanced equation for this reaction is the following: CaCO3(s) + 2HCl(aq) ---> CaCl2(aq) + CO2(g) + H2O(l)
A student would observe that the salt dissolves in water, forming a clear solution. When a calcium-containing salt dissolves, it may produce a white precipitate if reacted with a carbonate or phosphate solution, indicating the presence of calcium ions.
If chloride is present silver chloride with get precipitated..
The solution color of cupric oxide is blue to green.
The dihydrated salt is blue-green.

Well, hydrochloric acid is an acid, and calcium carbonate is a base. Therefore there is going to be a spontaneous reaction and will result in the formation of what is defined as a salt, namely calcium chloride and some water.
When aqueous ammonia is added in excess to a solution of silver chloride, the white precipitate of silver chloride dissolves to form a colorless, tetrahedral complex ion called [Ag(NH3)2]+. This complex ion is soluble in excess ammonia due to the formation of a stable coordination complex.
When hydrochloric acid reacts with calcium carbonate, it produces calcium chloride, carbon dioxide gas, and water. The balanced chemical equation for this reaction is: 2HCl + CaCO3 -> CaCl2 + CO2 + H2O. This reaction can be observed as fizzing or bubbling due to the release of carbon dioxide gas.
In the reaction between sodium bicarbonate and hydrochloric acid, one result of the reaction will be carbon dioxide bubbling out of solution. Also sodium chloride can be viewed falling in the solution.
Sounds like a great question to be answered with an experiment. Take equal amounts of ice in identical containers at the same temperature, sprinkle each set of ice cubes with equal amounts of the different substances, also at the same temperature, then observe which container of ice cubes melts the fastest. Here are more opinions and answers from other FAQ Farmers: * In my experience, calcium chloride melts ice fastest. Cat litter doesn't dissolve, so it obviously can't lower the freezing point of ice. * We did this experiment for school. We found out that calcium chloride did work the best, but rubbing alcohol and rock salt worked well, too. We also found out that the cat box litter did not work at all. All it did was absorb all the ice and water and make a big ice chunk.
