Ag+ (aq) + cl- (aq) → agcl (s) silver chloride is virtually insoluble in water so that the reaction appears to go to completion. how many grams of solid nacl must be added to 25.0 ml of 0.251 m agno3 solution to completely precipitate the silver?

0.367 g

Explanation:

Precipitation of silver and Cl requires 1:1 mol ratio of silver and Cl each, so the amount of mol NaCl (provides 1 mol of Cl⁻) and AgNO₃ (privides 1 mol of Ag⁺) must be equal for complete precipitation.

mol of Ag⁺ we have is

Thus we need 0.00625 mol of NaCl as well

The molar mass of NaCl is 58.44 g/mol

Therefore the total grams of NaCl needed is

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.
