99 Liters of water. If there are 20,000 ppm of iron nitrate in 1 liter of water then you would need to reduce the iron nitrate concnetration by a factor of 100. So since you are only adding water you need to have 100 times as much water than you had originally in order to dilute the concentration to 200 ppm. Since you have 1 liter already you need to add 99 more to get 100 times more water than you originally started with. You can also solve it using the following equation:
(Original Concnetration)*(Vol. original concentration) = (New concnetration)*(Original volume + amt of water to add)
20,000*1L = 200*(1L + X)20,000=200 + 200XSolving for X, X=99
Ag(NO3)(aq) + KI(aq) ---> K(NO3)(aq) + AgI(s)
Nitric Acid
The products of the reaction are solid calcium sulfate and aqueous lithium nitrate.
If the silver nitrate and ammonium chloride are both in solution when mixed, the very sparingly soluble silver chloride precipitates as a solid, leaving ammonium nitrate in the solution.
If the sodium sulfate and barium nitrate are both in solution in water, a precipitate of barium sulfate will be formed, because this salt is much less soluble in water than barium nitrate, sodium sulfate, or sodium nitrate.
When clhlorine is added to silver nitrate a milky white precipitate of Silver Chloride is formed. Potassium nitrate is also formed. When chlorine is added to potassium chloride nothing visible happens but the solutiuon become more acidic.
silver chloride should precipitate out.
The appearance of chromium will not change if added to the sodium nitrate since it cannot displace nitrate from the sodium.
No sodium nitrate is not harmful if added to soap. Sodium nitrate has been used in many products such as fertilizer and it is also added to food as a preservative.
Chromium will be reddish brown in appearance if added to sodium nitrate.
Amyl nitrate
20000
It becomes Barium Nitrate combined with Silver Chloride
Lead nitrate + potassium sulfate ---> Lead sulfate + Potassium nitrate
No
Zinc nitrate and silver are formed. Silver gets precipitated.
When a cooled saturated potassium nitrate solution is added to water, the concentration of the potassium nitrate decreases making it less likely that he substance will precipitate out of solution.
