Calcium deposits, primarily composed of calcium carbonate (CaCO 3), react with weak acids to form calcium salts that are soluble in water. The general reaction can be represented as follows: CaCO 3 + 2H + → Ca + 2 + CO 2 + H 2 O. Here, H + represents the hydrogen ions provided by the acid
Limescale build-up inside a pipe reduces both liquid flow and thermal conduction from the pipe, so will reduce thermal efficiency when used as a heat exchanger.. A descaling agent or chemical descaler is a liquid chemical substance used to remove limescale from metal surfaces in contact with hot water, such as in boilers, water heaters, and kettles.
Vinegar can also be used to clean hard surfaces and remove calcium deposits. Sulphuric acid is used in acidic drain cleaners to unblock clogged pipes by dissolving organic materials, like greases, proteins, and even carbohydrate-containing substances such as toilet tissue.
However, there is an equilibrium between dissolved calcium bicarbonate and dissolved calcium carbonate as represented by the chemical equation Ca 2+ + 2 HCO − 3 ⇌ Ca 2+ + CO 2− 3 + CO 2 + H 2 O. Note that CO 2 is dissolved in the water. Carbon dioxide dissolved in water (aq) tends to equilibrate with carbon dioxide in the gaseous state (g ...
The solvent to use is dependent on two factors: the agent that is causing the stain, and the material that has been stained. Different solvents will dissolve different stains, and the application of some solvents is limited by the fact that they not only dissolve the stain, but also dissolve the material that is stained as well.

Calcium oxalate is a combination of calcium ions and the conjugate base of oxalic acid, the oxalate anion. Its aqueous solutions are slightly basic because of the basicity of the oxalate ion. The basicity of calcium oxalate is weaker than that of sodium oxalate, due to its lower solubility in water.
The minimum amount of cardio exercise you can get away with each week depends on your resting heart rate and your specific fitness goals, according to trainers.
