Learning goal 2: Zinc chloride is mixed with potassium nitrate.Using the solubility chart, determine whether a precipitate will form.NoYes, potassium chlorideYes, zinc nitrate
Solution
To determine whether a precipitate will form when zinc chloride is mixed with potassium nitrate, we need to look at the possible products of this reaction and their solubility.
The reaction can be represented as follows:
ZnCl2 (aq) + 2 KNO3 (aq) -> Zn(NO3)2 (aq) + 2 KCl (aq)
The possible products are zinc nitrate (Zn(NO3)2) and potassium chloride (KCl).
According to the solubility rules, all nitrates (NO3-) are soluble, so zinc nitrate will not form a precipitate.
Also, all common salts of potassium (K+) are soluble, so potassium chloride will not form a precipitate either.
Therefore, no precipitate will form when zinc chloride is mixed with potassium nitrate.
