Do hydrochloric acid react with calcium?
Yes. When most metals react with dilute hydrochloric acid, metal chloride and hydrogen gas are the products. In the case of calcium, calcium chloride and hydrogen gas are produced.
What salt is formed when a solution of calcium hydroxide Ca is neutralized by hydrochloric acid HC1?
the salt formed when a solution of calcium hydroxide is neutralized by hydrochloric acid is calcium chloride. The formula for the calcium chloride formed is CaCl2. Other product formed will be hydrogen gas(H2) and water (H2O). This is because when an acid is neutralized by a hydroxide solution the resultant product should be a salt of the constituent metal(in our case, calcium), hydrogen gas, and water. The water will however not be formed if the mixture is only between a metal in the form of a solid and an acid; in this case only the salt and hydrogen gas are formed.
Is calcium sulphate a compound or an element?
Calcium sulphate is a compound. A compound is created when two or more elements are combined such as calcium and sulphide or sodium and chloride in the case of table salt.
Why is calcium carbonate insoluable?
It is a very good question indeed! You see calcium chloride in which calcium is attached to two chlorine atoms is water soluble and vice versa sodium carbonate in which two sodium atoms are attached to one carbonate is soluble. In one to one proportion, calcium chloride molecule is insoluble. Now the answer for this question may go like this. In case of calcium chloride calcium gives one electron to each of chlorine atom. Now both chlorine atoms would have one negative charge. So both of them will repel each other and form the ions of calcium and two chlorine. Thus making them soluble. In case of sodium carbonate, two sodium atoms give electrons to carbonate. Now both sodium ions become positively charged and and would repel each other. So they would form ions along with carbonate. So sodium carbonate has become soluble. Now in case of calcium carbonate, calcium would like to give away 2 electrons but carbon becomes much electrically negative if it takes the electrons. So in this case no repelling force is there to help the metal, it surrenders and form sort of covalent bond and thus ions are not formed. So calcium carbonate is insoluble in water.
When salt is dissolved in water the water is the?
Water would be the solvent in this case.

What is the chemical name for calcium salt?
The name for calcium carbonate is calcium carbonate. The formula is CaCO3
How is sea salt and sodium chloride different?
Chloride is a negative ion Cl- . It must be paired with a positive ion to form a complete substance. In the case of sodium chloride that ion is sodium, Na+ . Other chloride salts such as potassium chloride, calcium chloride, and ammonium chloride also exist. As its own element it is called chlorine, which is electrically neutral and takes the form of a toxic green gas, Cl2 .

What does Nitric acid plus calcium hydroxide yield?
An acid reacting with a hydroxide will result in the formation of water and the corresponding salt of the hydroxide's cation and the acid's anion. So in this case the products are water and calcium nitrate.
What in salt makes ice melt?
Salt is made up of Sodium Chloride (NaCl). In this case, it is the Chloride (Cl) that breaks the composition of water, and causes the freezing point of water to be lowered. Without Chloride, the freezing point of water is 32 degrees Fahrenheit (0 Celcius). With 10% of Sodium Chloride (salt), water freezes at 20 Fahrenheit. With 20% of Sodium Chloride, water freezes at 2 Degrees Fahrenheit.
CuCO3 plus HCl equals?
calcium carbonate + hydrochloric acid -> Carbon dioxide + Water+ Calcium Chloride In general, when a carbonate is added to an acid, the equation will be carbonate + acid -> salt + water + carbon dioxide
What does 800 milliliters of salt mean?
1. A volume of powdered sodium chloride.2. A volume of water solution of sodium chloride with a non-specified concentration in this case..
Is calcium sulfate an element?
No, because it has 2 substances in it - calcium and sulfate - Calcium is an element, but sulfate is a polyatomic ion. Sulfate consists of sulfur and oxygen. Therefore, calcium sulfate is a compound, that is, made of three elements.
