ii. When anhydrous Beryllium chloride is exposed to air, it readily forms Beryllium hydroxide. The equation would be:
BeCl2 + 2H2O --> Be(OH)2 + 2 HCl
**H2O is the water in the air.
Now the solution will now be acidic so upon the addition of Sodium Hydroxide, the reaction will be neutralized. The neutralization equation is:
HCl + NaOH --> NaCl + H2O
ii. The reaction of Sodium iodide with Silver nitrate will produce a precipitate. The reaction equation can be written as:
NaI (aq) + AgNO3 (aq) ---> NaNO3 (aq) + AgI (s)
AgI is the precipitate in the solution.
When aqueous Ammonia is added, no visible changes will occur since ammonia cannot dissolve the precipitate AgI in the solution.
