Another reason that DM water is more agressive in terms of corrosion to carbon steel is that it contains almost no calcium or magnesium. Presence of calcium or magnesium in water tends to form a passive film of calcium or magnesium salts on the metal surface which to some extent protects the metal …

Concrete degradation - Wikipedia
Concrete degradation may have various causes. Concrete can be damaged by fire, aggregate expansion, sea water effects, bacterial corrosion, calcium leaching, physical damage and chemical damage (from carbonatation, chlorides, sulfates and non-distilled water). This process adversely affects concrete exposed to these damaging stimuli.

A challenging Chem Problem? | Yahoo Answers
2007/12/13· b)A small piece of calcium metal is added to hot distilled water. When a metal (calcium) reacts with water, the products are metal hydroxide and hydrogen gas. So; Ca + 2H2O → Ca(OH)2 + H2↑ c) A solution of copper(II) chloride is added to a solution of
Acid Base Salt NCERT InText solution-1 - EXCELLUP
Metal compound A reacts with dilute hydrochloric acid to produce effervescence. The gas evolved extinguishes a burning candle. Write a balanced chemical equation for the reaction if one of the compounds formed is calcium chloride. Answer: When calcium carbonate reacts with hydrochloric acid, it produces carbon dioxide gas with effervescence.
Living Science 2019 2020 for Class 8 Science Chapter 4 - …
Answer: When metal M 3 is reacted with a salt of metal M 4 then it displaces metal M 4 from its salt solution and salt of metal M 3 is formed. But when metal M 4 is reacted with a salt of metal M 3, no reaction takes place.Hence, metal M 3 is more reactive than metal M 4, because it displaced metal M 4 from its salt solution but metal M 4 could not displace metal M 3 from its salt solution.
Lab 10 - Solubility Product for Calcium Hydroxide
To prepare the saturated Ca(OH) 2 solution, use your forceps to safely add a small piece of calcium metal to 150 mL of distilled water in a beaker. If you add too much metal, a large excess of calcium hydroxide solid can form and be difficult to remove by filtration.
Calcium | Article about calcium by The Free Dictionary
Calcium reacts with cold water rapidly at first, but the reaction is then retarded because of the formation of a film of Ca(OH) 2. Calcium reacts vigorously with hot water and with acids, giving off H 2 (this does not occur with concentrated HNO 3).
Alizarin-Red Staining Solution Alizarin red is a commonly …
Alizarin Red, an anthraquinone derivative, may be used to identify calcium in tissue sections and cultured cells in vitro. The reaction is not strictly specific for calcium, since magnesium, manganese, barium, strontium, and iron may interfere, but these elements usually do not occur in sufficient concentration to interfere with the staining.
The Reaction Of An Acid With A Metal | Reactions Of …
A possible extension is to hold a cold piece of metal or glass above the place where you burst the bubbles so that the water vapour that forms during the reaction condenses on the metal or glass. Place approximately 1 g of the magnesium pieces in the test tube, but do not add the hydrochloric acid until everything else is ready to be asseled.

Water softening - Wikipedia
Water softening is the removal of calcium, magnesium, and certain other metal ions in hard water.The resulting soft water requires less soap for the same cleaning effort, as soap is not wasted bonding with calcium ions. Soft water also extends the lifetime of pluing by reducing or eliminating scale build-up in pipes and fittings.
