Does a precipitate form if HCl and Ba(NO3)2 are mixed?
No. Consult the solubility rules.

To determine if a precipitate will form when HCl and Ba(NO3)2 are mixed, we can use the solubility rules.
Let's first write the balanced chemical equation for the reaction:
HCl + Ba(NO3)2 -> BaCl2 + HNO3
According to the solubility rules, most chloride salts are soluble, while most nitrates are also soluble. However, there are exceptions. Barium chloride (BaCl2) is considered insoluble in water.
Therefore, when HCl (hydrochloric acid) is mixed with Ba(NO3)2 (barium nitrate), a precipitate of BaCl2 (barium chloride) will form because it is insoluble.
To summarize, yes, a precipitate will form when HCl and Ba(NO3)2 are mixed, which is BaCl2.
To determine whether a precipitate forms when HCl (hydrochloric acid) and Ba(NO3)2 (barium nitrate) are mixed, we need to examine the solubility rules. These rules indicate the solubility of different compounds in water.
First, let's identify the ions present in the reactants:
- HCl dissociates into H+ cations and Cl- anions.
- Ba(NO3)2 dissociates into Ba2+ cations and NO3- anions.
Now, let's consult the solubility rules to determine if a precipitate will form. According to the typical solubility rules:
1. Most chloride (Cl-) salts are soluble, except for those of silver (Ag+), lead (Pb2+), and mercury (Hg2+).
2. Most nitrate (NO3-) salts are soluble, making Ba(NO3)2 soluble.
Since both HCl and Ba(NO3)2 are soluble in water, when they are mixed, no precipitate will form. The reaction will simply result in the formation of a solution containing H+ and Cl- ions from HCl, as well as Ba2+ and NO3- ions from Ba(NO3)2.
