Four ions exist: Na+, Cl-, Ag+, (NO3)-; sodium chloride react with silver nitrate:
NaCl + AgNO3 = AgCl + NaNO3
AgCl is insoluble in water.
The silver nitrate solution (AgNO3) provides the silver in silver chloride.
agno3
NaCI + AgNO3 >>>>> NaNO3 + AgCI (white ppt.)
Get moles silver nitrate. 255 grams AgNO3 (1 mole AgNO3/169.91 grams) = 1.5008 moles AgCO3 --------------------------------Now; Molarity = moles of solute/Liters of solution ( 1500 ml = 1.5 Liters ) Molarity = 1.5008 moles AgNO3/1.5 Liters = 1.00 M AgNO3 ---------------------
Molarity = moles of solute/liters of solution or, for our purposes moles of solute = liters of solution * Molarity moles of AgNO3 = 0,50 liters * 4.0 M = 2.0 moles of AgNO3 needed --------------------------------------
no because emf of cu ic less as compared to Agno3 as we keep agno3 in cu reaction will occour
Balanced equation first! AgNO3 + NaCl -> AgCl + NaNO3 all one to one, get moles AgNO3 3.82 moles NaCl (1 mole AgNO3/1 mole NaCl) = 3.82 moles AgNO3 ------------------------------- Molarity = moles of solute/Liters of solution 0.117 M AgNO3 = 3.82 moles AgNO3/Liters Liters = 3.82/0.117 = 32.6 Liters which is 32600 milliliters which is unreasonable; check answer if you can
Howe's solution- ammoniacal AgNo3-dental protective mixed with 1o% Formalin or Eugenol
The balanced equation is as follows: KIO3 + AgNO3 --> KNO3 + AgIO3
They will form NaNO3 in aqueous solution, and AgOH would precipitate out of solution. AgNO3(aq) + NaOH(aq) --> AgOH(s) + NaNO3(aq) This is an example of a double displacement/replacement reaction.
