Based on sulubility rules, which of the
followingwill occur when solutions of znso4(aq)
andmgcl2(aq) are mixed? write the nie if aprecipitation
is considered likely.
a. zncl2 wil
precipitate; mg2andso42_ will be
spectatior ions.
b. znso4 will precipitate; mg2+ andcl-
will be spectator ions.
c. mgso4 will precipitate; zn2+and cl-
will be spectator ions.
d. mgcl2 will precipitate; zn2+
andso42- will be spectator ions.
e. no precipitate will form.

The correct option is: E. No precipitate will form.

Explanation:

A solubility chart refers to the list of solubility of various ionic compounds. It shows the solubility of the various compounds in water at room temperature and 1 atm pressure.

Also, according to the solubility rules, the salts of chlorides, bromides and iodides are generally soluble and mostly all salts of sulfate are soluble.

Since, all the compounds formed in this double replacement reaction are soluble in water. Therefore, no precipitate will be formed.
