litmus
Bauxite is aluminum ore, hematite is iron ore.
PbS. Lead (II) Sulfate is insoluble in acidic solutions
Litmus solution is obtained from lichens. It is used to test whether the solution is acidic or basic.
to determine accuracy of a reaction to access how successful the reaction is to know the amount of material to be obtained if efficiency level is at 100%
The list is nearly endless: fuels, plastics, medicines, detergents, explosives, pesticides, fertilizers, tires, road tar, roofing tar, etc.
litmus
The new solutions obtained have other concentrations for solutes.
oxidation
These salts are obtained from solutions evaporating the water.
Evaporating the water salts are obtained from the solutions.
saphir
Bauxite is aluminum ore, hematite is iron ore.
An example: by precipitation from solutions of NH4F and Mg(NO3)2
