Because sodium chloride is a true cheap preservative for foods; also in reasonable amounts it is not dangerous.
For example sodium chloride or sodium bicarbonate.
For example sodium chloride or sodium bicarbonate.
the mixture between the two creates a safe neutral compound
Depending on the concentration and the rules in each country.
nope. too much concentration of sodium chloride once it gets into your mucous membrane like the mouth may have only some kind of metallic taste and so minimal effect on the eyes also since you can even open your eyes under sea water. its a solution of choice for diluting drugs since its safe and non-erosive.
Nope, it's very safe. You always eat it, because its in your common salt
No. Calcium chloride is a cousin of sodium chloride- table salt. Likely to increase the hazard of RUST. There are other materials, such as silica gel, that are effective means of contolling moisture. But calcium chloride is not.
Yes, but in the form of sodium chloride. Sodium chloride is table salt, and is contained in many foods. Only very small amounts are needed in the human diet, on a daily basis. In civilized societies, with their processed foods, most people eat too much salt.
Not directly. However there are edible products made with very small amount of this solution. By the way it's "Potassium Carbonate and Sodium Bi-Carbonate solution" AKA: alkaline water. Not Potassium Bi-carbonate.
no, its not safe to dispose nuclear waste in water,rather it would be safe to dispose it in common salt trenches.
Salt is very safe. It will not explode and is stable. It will react with iron and cause it to rust, but at a fairly slow rate. Digesting some salt is vital for life. Too much salt can cause health issues.
