Mixtures of calcium salts and sodium alginate can be made to set to a gel at different rates, depending on the rate at which the calcium salt dissolves. Gel formation can also be delayed even after everything is mixed together; this is done using a gel-retarder that reacts with the calcium before the alginate does, so no calcium is available to the alginate until all the retarder is used.

Calcium chloride is a common salt that is often used to melt ice from roads and sidewalks. Calcium chloride isn''t a food-grade salt, but it isn''t toxic. High concentrations of calcium chloride can harm plants and trees near roadways.
Is Calcium Chloride safe to use on roof or gutter ice …
Calcium Chloride (CaCl) is corrosive to certain metals and really should not be used on rooftops for a couple of reasons: Roofing nails are basically zinc coated iron (galvanized). Calcium chloride will eventually corrode these. Another concern is that after melting
Calcium and magnesium use in aquaculture « Global …
Calcium ions affect the toxicity of trace metals to fish and other aquaculture species. The presence of calcium blocks the uptake of metal ions across the gills, thereby increasing the dissolved concentration of metals required to cause a toxic effect.

The name of the salt formed by these ions must include the name of the metal AND its charge: iron(1+) chloride, iron(2+) chloride, iron(3+) chloride. Iron can also form covalent compounds. In this case there is no ion, no positive charge, but we can assign an informal charge based on its oxidation state (which is then referred to as its oxidation state or oxidation nuer).
