In summary, a precipitate will form in reactions a and c: a. \(Hg_{2}(NO_{3})_{2} + CuSO_{4}\) will form \(Hg_{2}SO_{4}\) as a precipitate. c. \(K_{2}CO_{3} + MgI_{2}\) will form \(MgCO_{3}\) as a precipitate.

Step by step solution

01

a. Hg₂(NO₃)₂(aq) + CuSO₄(aq)

In this case, let's consider the possible double replacement reaction products: - Hg₂SO₄ and Cu(NO₃)₂ Now, let's apply the solubility rules: - Hg₂SO₄ is insoluble (rule: most sulfates are soluble, except for BaSO₄, PbSO₄, Hg₂SO₄, and CaSO₄) - Cu(NO₃)₂ is soluble (rule: all nitrates are soluble) Since Hg₂SO₄ is insoluble, a precipitate will form in this case.
02

b. Ni(NO₃)₂(aq) + CaCl₂(aq)

The possible double replacement reaction products are: - NiCl₂ and Ca(NO₃)₂ Let's use the solubility rules: - NiCl₂ is soluble (rule: all chlorides are soluble, except for AgCl, PbCl₂, and Hg₂Cl₂) - Ca(NO₃)₂ is soluble (rule: all nitrates are soluble) Since both products are soluble, no precipitate will form in this case.
03

c. K₂CO₃(aq) + MgI₂(aq)

The possible double replacement reaction products are: - KI and MgCO₃ Let's apply the solubility rules: - KI is soluble (rule: all alkali metal salts are soluble) - MgCO₃ is insoluble (rule: most carbonates are insoluble, except for those of alkali metals and ammonium) Since MgCO₃ is insoluble, a precipitate will form in this case.
04

d. Na₂CrO₄(aq) + AlBr₃(aq)

The possible double replacement reaction products are: - NaBr and Al₂(CrO₄)₃ Let's apply solubility rules: - NaBr is soluble (rule: all alkali metal salts are soluble) - Al₂(CrO₄)₃ is soluble (rule: most chromates are insoluble, except for those of alkali metals and ammonium) Since both products are soluble, no precipitate will form in this case. In summary, a precipitate will form in reactions a, and c: a. Hg₂(NO₃)₂ + CuSO₄ will form Hg₂SO₄ as a precipitate. c. K₂CO₃ + MgI₂ will form MgCO₃ as a precipitate.

A 0.500 -L sample of \(\mathrm{H}_{2} \mathrm{SO}_{4}\) solution was analyzed by taking a 100.0 -mL aliquot and adding 50.0 \(\mathrm{mL}\) of 0.213 \(\mathrm{M}\) NaOH. After the reaction occurred, an excess of \(\mathrm{OH}^{-}\) ions remained in the solution. The excess base required 13.21 \(\mathrm{mL}\) of 0.103 \(\mathrm{M}\) \(\mathrm{HCl}\) for neutralization. Calculate the molarity of the original sample of \(\mathrm{H}_{2} \mathrm{SO}_{4}\) . Sulfuric acid has two acidic hydrogens.

A sample may contain any or all of the following ions: \(\mathrm{Hg}_{2}^{2+}\) \(\mathrm{Ba}^{2+}\) and \(\mathrm{Mn}^{2+}\) a. No precipitate formed when an aqueous solution of NaCl was added to the sample solution. b. No precipitate formed when an aqueous solution of $\mathrm{Na}_{2} \mathrm{SO}_{4}$ was added to the sample solution. c. A precipitate formed when the sample solution was made basic with NaOH. Which ion or ions are present in the sample solution?

Write the balanced formula, complete ionic, and net ionic equations for each of the following acid–base reactions. a. \(\mathrm{HNO}_{3}(a q)+\mathrm{Al}(\mathrm{OH})_{3}(s) \rightarrow\) b. $\mathrm{HC}_{2} \mathrm{H}_{3} \mathrm{O}_{2}(a q)+\mathrm{KOH}(a q) \rightarrow$ c. \(\mathrm{Ca}(\mathrm{OH})_{2}(a q)+\mathrm{HCl}(a q) \rightarrow\)

The units of parts per million (ppm) and parts per billion (ppb) are commonly used by environmental chemists. In general, 1 ppm means 1 part of solute for every \(10^{6}\) parts of solution. Mathematically, by mass: $$\mathrm{ppm}=\frac{\mu \mathrm{g} \text { solute }}{\mathrm{g} \text { solution }}=\frac{\mathrm{mg} \text { solute }}{\mathrm{kg} \text { solution }}$$ In the case of very dilute aqueous solutions, a concentration of 1.0 \(\mathrm{ppm}\) is equal to 1.0\(\mu \mathrm{g}\) of solute per 1.0 \(\mathrm{mL}\) , which equals 1.0 \(\mathrm{g}\) solution. Parts per billion is defined in a similar fashion. Calculate the molarity of each of the following aqueous solutions. a. 5.0 \(\mathrm{ppb} \mathrm{Hg}\) in \(\mathrm{H}_{2} \mathrm{O}\) b. 1.0 \(\mathrm{ppb} \mathrm{CHCl}_{3}\) in \(\mathrm{H}_{2} \mathrm{O}\) c. 10.0 \(\mathrm{ppm}\) As in \(\mathrm{H}_{2} \mathrm{O}\) d. 0.10 $\mathrm{ppm} \mathrm{DDT}\left(\mathrm{C}_{14} \mathrm{H}_{9} \mathrm{C} 1_{5}\right)\( in \)\mathrm{H}_{2} \mathrm{O}$
