Calcium Carbonate + Hydrochloric Acid --> Calcium Chloride + Water + Carbon Dioxide. You would see the Calcium Carbonate slowly dissolve and the Carbon Dioxide being made as bubbles. But you would not see the Calcium Chloride or the water being made since there is already water in the flask and the C al cium Chloride will dissolve in it.

The Reaction of Metals with Water. Potassium, sodium, lithium and calcium react with cold water, see alkali metals and alkaline earth metals. Metals in the reactivity series from magnesium to iron react with steam - H 2 O (g) but not water - H 2 O (l). The reaction .
What happens when calcium is treated with water?(i) It …
In general, metals form a metal oxide and hydrogen gas and this metal oxide when soluble in water dissolve further forming a metal hydroxide. But some metals form metal hydroxide directly. In the case of calcium, the reaction with water is less violent and hydrogen starts floating on water and bubbles of hydrogen gas will stick to the metal surface.
Calcium carbonate - Essential Chemical Industry
Calcium carbonate (limestone) is heated to form calcium oxide (quicklime) and carbon dioxide: It is an endothermic reaction and the equilibrium lies far to the left at low temperatures. Only at about 1200 K does the partial pressure of carbon dioxide exceed
Reaction of Metals with Water, Steam and Dilute Acids
A) Reaction of Metals with Cold Water or Steam The more reactive metals tend to react with cold water to form metal hydroxide (alkaline solution) and hydrogen gas. This reaction can be easily represented by the following word equation: Metal + Water → Metal

What Metals React With Water to Produce Hydrogen? | …
When sodium metal reacts with water, the resulting heat melts the metal almost immediately into a grey-silver ball. The hydrogen gas evolved during this reaction propels the ball rapidly across the surface of the water, leaving a white trail of sodium hydroxide that eventually dissolves into a clear solution.
Determining Calcium Ion Concentration in Water …
Calcium and magnesium ions dissolved in water cause water hardness. Ethylenediaminetetraacetic acid (EDTA), shown on the right in its deprotonated form, is commonly used in a titration to determine the concentration of Ca 2+ and Mg 2+ ions in water because both ions form complexes with EDTA.
Calcium - Periodic table
Calcium is reactive and, for a metal, soft. With a bit of effort, it can be cut with a sharp knife. In contact with air, calcium develops a mixed oxide and nitride coating, which protects it from further corrosion. Calcium reacts easily with water and acids and the metal
