Asolution is prepared by mixed by mixing 0.10l of 0.14m sodium chloride with 0.21l of a 0.19m mgcl2 solution. what volume of 0.21m silver nitrate is required to precipitate all the cl- ion in the solution agcl?

Explanation:

If is the molarity and is the molarity of a given solution,

number of moles of the solute in the solution is .

Number of moles of ions in the initial solution is the sum of number of moles of ions  in and

Number of moles of ions in is

number of moles of ions  in is

Number of moles of ions in the initial solution is

So, of ions are required to displace of ions.

So,number of moles of required is

So,

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
