CaCo3  Ca2+ + Co32- In this investigation the substance that is formed is Calcium Chloride, Water and Carbon Dioxide. The salts of hy­drochlo­ric acid are called chlo­rides. 2HCl (aq) + CaCO3(s) → CaCl2 (aq) + CO2(g)  Improvements This compound has a carbonate ion, which has a charge of -2 and a calcium ion, What affects reaction rate? The combination of the acid naturally produced by the stomach and the base ingested in the form of calcium carbonate, either through a food source or a mineral supplement, will cause the neutralization of both compounds and the creation of by-products that are neither acidic nor basic. Dolostone is a rock composed of almost entirely of dolomite. Lime scale can be one of the most difficult materials to remove from porcelain and tile. Hypothesis 3  Results Tables Hydrochloric acid is found naturally in gastric acid. Aim 3 hydrochloric acid + calcium hydroxide -> calcium chloride + water. Hydrochloric acid or muriatic acid is a colorless inorganic chemical system with the formula HCl.

Hydrochloric acid cleaners are not safe for all surfaces. Year 10 Science Term 1 – Using Chemistry Hydrochloric acid is a versatile chemical that hydrochloric acid is used in the chemical industry as a chemical reagent in the large-scale production of vinyl chloride (CH 2 CHCl) for PVC plastic, and polyurethane. Wa­ter is mixed with cal­ci­um ox­ide to yield cal­ci­um hy­drox­ide. Method 6 Background Knowledge:  Aim Assembled apparatus for the generation of HCl (g) Hydrogen chloride is an important chemical of interest not only by itself but also for preparative purposes. It causes severe skin burns and eye damage.  Conclusions It is a highly corrosive, strong mineral acid with many industrial uses. As water forms, the number of free hydrogen ions in the stomach decreases, creating a less acidic environment. Materials 4 Background Information: Hydrochloric acid is a clear, colourless, highly-pungent solution of hydrogen chloride (HCl) in water. The rate of reaction is a measure of how quickly a reaction happens. Evaluation When work­ing with strong acids, you should al­ways have neu­tral­iz­ers at hand – weak al­ka­line so­lu­tions, sodi­um bi­car­bon­ate (bak­ing soda), etc. It reacts with oxidizers releasing chlorine gas. CaCO + 2HCl CaCl + H O + CO Concentrated hydrochloric acid dissolves many metals and forms oxidized metal chlorides and hydrogen gas. Analysis and Conclusions Year 10 Term 1 - Using Chemistry Rate of reaction between Hydrochloric Acid and Calcium Carbonate Calcium carbonate reacts with hydrochloric acid to form carbon dioxide gas. In in­dus­try, the cal­ci­um ox­ide need­ed for the above process is pro­duced via cal­ci­na­tion. A pure source, com­mon­ly mar­ble, is usu­al­ly used to ob­tain the cal­ci­um car­bon­ate used in food col­or­ing. affects the rate of reaction by measuring the amount of gas produced This reaction is fairly rapid and energetic at high concentrations, in large part due to the high affinity of calcium ions for chloride ions. To Investigate the rate of reaction between Calcium Carbonate and My hypothesis was that if the surface area to volume ratio of calcium carbonate was increased, then the rate of the reaction will increase because there are more particles that are accessible by the hydrochloric acid, thus more particles that can react with each other.  Extending the Investigation Keep your bathroom free of lime scale with a hydrochloric acid cleaner.
