WebThe molar mass of water (H2O) can be determined by adding up the atomic masses of each element present in the compound. Water is composed of two hydrogen atoms (H) and one oxygen atom (O). The atomic mass of hydrogen is 1.008 amu (atomic mass units). The atomic mass of oxygen is 16.00 amu. Therefore, the total mass of water is: WebA.) FeCl2 is water soluble. what ions are formed when this compound dissolves in water? B.) If the solution is 0.255 M FeCl2 what is the molarity of each ion in aqueous solution?
If the concentration of a FeCl_3 solution is 2.5 M, what is the ...
WebFeCl2 is not really a coagulant.It is used in water treatment to precipate sulfide and in wastewater treatment plant to precipate phosphate, but it is very ineffective as coagulant. … WebDec 30, 2024 · Ferrous chloride (FeCl2) is used in pharmaceutical preparations, for sewage treatment, and as a mordant (which fixes dyes so that they will not run) in textiles. Preparation Iron (II) chloride is prepared by passing chlorine or hydrogen chloride gasover iron at red heat or 700°C: Fe + 2HCl → FeCl 2 + H 2 Fe + Cl 2 → FeCl 2 edward feser marx
