Answer 1

The kind of reaction that occurs when you mix aqueous solutions of barium sulfide and sulfuric acid is a precipitation reaction.

Further Explanation

• The chemical reaction between Ba(OH)2(aq) and H2SO4(aq) is given by;

Ba(OH)₂(aq) + H₂SO4(aq) --> BaSO₄(aq) + 2H₂O(l)

• This is a type of precipitation reaction, where a precipitate is formed after the reaction, that is Barium sulfate.

Other types of reaction

Neutralization reactions

• These are reactions that involve reacting acids and bases or alkali to form salt and water as the only products.
• For example a reaction between sodium hydroxide and sulfuric acid.

NaOH(aq) + H₂SO₄(aq) → Na₂SO₄(aq) + H₂O(l)

Displacement reactions

• These are reactions in which a more reactive atom or ion displaces a less reactive ion from its salt.

Mg(s) + CuSO₄(aq) → MgSO₄(aq) + Cu(s)

Redox reactions

• These are reactions that involve both reduction and oxidation occuring simultaneously durin a chemical reaction.
• For example,

Mg(s) + CuSO₄(aq) → MgSO₄(aq) + Cu(s)

• Magnesium atom undergoes oxidation while copper ions undergoes reduction.

Decomposition reactions

• These are type of reactions that involves breakdown of a compound into its constituents elements.

• For example decomposition of lead nitrate.

Pb(NO3)2(S) → PbO(s) + O2(g) + NO2(g)

Answer 2

The reactions that occur by mixing aqueous solutions of barium sulfide and sulfuric acid are

$\boxed{{\text{Precipitation and gas evolution reactions}}}$

Further Explanation:

Precipitation reaction:

It is the type of reaction in which an insoluble salt is formed by the combination of two solutions containing soluble salts. That insoluble salt is known as precipitate and therefore such reactions are named precipitation reactions. An example of precipitation reaction is,

${\text{AgN}}{{\text{O}}_3}\left( {aq}\right)+{\text{KBr}}\left( {aq}\right)\to {\text{AgBr}}\left( s \right)+{\text{KN}}{{\text{O}}_3}\left( {aq}\right)$

Here, AgBr is a precipitate.

Neutralization reaction:

It is the reaction that occurs between an acid and a base in order to form salt and water. It is named so as it neutralizes the excess amount of hydrogen or hydroxide ions present in the solution. It is used to decrease the acidity in the stomach, wastewater treatment, antacid tablets and to control the pH of soil. An example of neutralization reaction is,

${\text{HCl}}+{\text{NaOH}}\to{\text{NaCl}}+{{\text{H}}_2}{\text{O}}$

Gas evolution reaction:

It is the type of chemical reaction in which one of the products is a gas. These reactions are often carried out in a fume chamber if poisonous gases are produced. An example of gas evolution reaction is,

${\text{Zn}}+2{\text{HCl}}\to{\text{ZnC}}{{\text{l}}_2}+{{\text{H}}_2}$

Here, ${{\text{H}}_2}$ is evolved so it is a gas evolution reaction.

The solubility rules to determine the solubility of the compound are as follows:

1. The common compounds of group 1A are soluble.

2. All the common compounds of ammonium ion and all acetates, chlorides, nitrates, bromides, iodides, and perchlorates are soluble in nature. Only the chlorides, bromides, and iodides of  ${\text{A}}{{\text{g}}^ + }$ , ${\text{P}}{{\text{b}}^{2 + }}$ , ${\text{C}}{{\text{u}}^ + }$ and ${\text{Hg}}_2^{2 + }$ are not soluble.

3. All common fluorides, except for ${\text{Pb}}{{\text{F}}_{\text{2}}}$ and group 2A fluorides, are soluble. Moreover, sulfates except ${\text{CaS}}{{\text{O}}_{\text{4}}}$ , ${\text{SrS}}{{\text{O}}_{\text{4}}}$ , ${\text{BaS}}{{\text{O}}_{\text{4}}}$ , ${\text{A}}{{\text{g}}_{\text{2}}}{\text{S}}{{\text{O}}_{\text{4}}}$ and ${\text{PbS}}{{\text{O}}_{\text{4}}}$ are soluble.

4. All common metal hydroxides except ${\text{Ca}}{\left( {{\text{OH}}}\right)_{\text{2}}}$ , ${\text{Sr}}{\left( {{\text{OH}}} \right)_{\text{2}}}$ , ${\text{Ba}}{\left( {{\text{OH}}} \right)_{\text{2}}}$  and hydroxides of group 1A, are insoluble.

5. All carbonates and phosphates, except those formed by group 1A and ammonium ion, are insoluble.

6. All sulfides, except those formed by group 1A, 2A, and ammonium ion are insoluble.

7. Salts that contain ${\text{C}}{{\text{l}}^ - }$ , ${\text{B}}{{\text{r}}^ - }$ or ${{\text{I}}^ - }$ are usually soluble except for the halide salts of ${\text{A}}{{\text{g}}^ + }$ , ${\text{P}}{{\text{b}}^{2 + }}$ and ${\left({{\text{H}}{{\text{g}}_2}}\right)^{{\text{2 + }}}}$.

8. The chlorides, bromides, and iodides of all the metals are soluble in water, except for silver, lead, and mercury (II). Mercury (II) iodide is water insoluble. Lead halides are soluble in hot water.

9. The perchlorates of group 1A and group 2A are soluble in nature.

10. Almost all the sulfides of transition metals are highly insoluble. These include CdS, FeS, ZnS, and ${\text{A}}{{\text{g}}_2}{\text{S}}$. The sulfides of arsenic, antimony, bismuth, and lead are also insoluble.

11. All the acetates and chlorates are soluble in nature.

The reaction between barium sulfide and sulfuric acid is as follows:

${\text{BaS}}\left({aq} \right)+{{\text{H}}_2}{\text{S}}{{\text{O}}_4}\left( {aq}\right) \to {\text{BaS}}{{\text{O}}_4}\left( s \right)+{{\text{H}}_2}{\text{S}}\left( g \right)$

According to the solubility rules, ${\text{BaS}}{{\text{O}}_4}$ is an insoluble salt. So ${\text{BaS}}{{\text{O}}_4}$ will form precipitate in the above reaction and therefore this is a precipitation reaction.

Also, ${{\text{H}}_2}{\text{S}}$ is evolved during this reaction, so it is also a gas evolution reaction.
