No, calcium chloride is CaCl2 containing calcium ions (Ca2+) and chloride ions (Cl-). A sulfite must contain sulfite ions (SO32-)
Iodine
A student would observe that the salt dissolves in water, forming a clear solution. When a calcium-containing salt dissolves, it may produce a white precipitate if reacted with a carbonate or phosphate solution, indicating the presence of calcium ions.
Household items that contain alkali earth metals include toothpaste (fluoride containing calcium), antacids (containing magnesium or calcium), and some cleaning agents (containing calcium, magnesium, or barium).
Salt marshes, estuaries.
A substance containing sodium fluoride could be a toothpaste, mouthwash, or fluoride supplement. Sodium fluoride is commonly used in oral care products to help prevent tooth decay and strengthen tooth enamel.
Technically salt does not react with water. It will dissolve in water which is not the same thing as causing a chemical reaction. Calcium by itself does not react with salt water -- it is dissolved into the water and is a crucial element of life for many salt-water species. Some compounds containing calcium may react with (or in) salt water.
To help prevent calcium stones from forming, your doctor may prescribe a thiazide diuretic or a phosphate-containing preparation. Drink more water. Reduce your salt use. Talk to your Doctor about a diet low in animal proteins and salt.
The salt formed by the reaction of calcium hydroxide and sulfuric acid is calcium sulfate. The formula of this salt is CaSO4. Calcium sulfate is a white in appearance when pure.
Sea salt doesn't contain calcium silicate; calcium silicate can be added to salt as an anticaking agent.
Pasteur salt is a mixture of calcium and potassium phosphates, ammonium tatrate, magnesium sulfate in water.
