How many ml of a 0.175 m fecl3 solution are needed to make 250. ml of a solution that is 0.300 m in cl- ion? can ya'll explain how to find the answer to this?

The volume of FeCl₃ needed to make 250 mL of 0.3 M in Cl⁻ ions was 142,857 ml

Dilution is the process of adding solvents (generally water) which aims to obtain a solution with a concentration that is smaller than the initial concentration of a more concentrated substance.

So the principle of dilution is to get a lower / dilute concentration.

At dilution the number of dissolved moles before and after dilution is the same

The dilution formula is as follows:

M1 = Molarity of the solution before dilution

V1 = Volume of solution before dilution

M2 = Molarity of solution after dilution

V2 = Volume of Molarity of solution after dilution

Ionization reaction on FeCl₃

FeCl₃ -> Fe³⁺ + 3Cl⁻

For 0.175 M FeCl₃ there are 3.0,175 M Cl⁻ = 0.525 M Cl⁻

Because what is needed is a 250 ml 0.3 M Cl⁻ solution, then we use the dilution formula:

M1V1 = M2V2

0.525. V1 = 250. 0.3

V1 = 142,857 ml

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
