Acids Bases and Salts Test - 23

Indigestion is a term generally used for stomach pain and heartburn, indigestion is mainly due to the increased acidity in the stomach. To treat indigestion we use a special kind of drug category which is named ‘Antacids’. 

Antacids actually are base-containing drugs who neutralizes the hyper acidic condition. Eg, milk of magnesia (Mg(OH)₂).

Hence, the correct option is (B).

Acids cannot be stored in metal containers as they will react with the metal, forming metal salt and liberating Hydrogen gas. Strong acids are also corrosive in nature so they cause corrosion on the container. 

Containers made of glass and ceramics are ideal for storage of acid due to its chemical inertness and resistant to corrosion. 

Hence, the correct option is (C).

An acid is a substance that dissociates in aqueous solution, releasing the hydrogen ion H⁺(a proton):

$HA\rightleftharpoons A^{-}+H^{+}$

Conversely, strong bases react completely with water to produce the hydroxide ion (OH^-).

Hence, the correct option is (B).

Acids cannot be stored in metal containers as they will react with the metal, forming metal salt and liberating Hydrogen gas. Containers made of glass are ideal for storage of acid due to its chemical inertness.

In the given options HCl, HNO₃, and H₂SO₄ all are very strong acids who are also very corrosive in nature so cannot be stored in the metal containers. 

Hence, the correct option is (D).

Glucose and alcohol do not conduct electricity in their aqueous solution because they do not dissociate into their ions or they do not give their H⁺ ion.

In glucose and alcohol hydrogen atom is present but does not give hydrogen ion into their aqueous solution. 

Hence, the correct option is (C). 

Compounds like alcohol and glucose do not dissociate in water to form hydrogen ions. This is proved due to the fact that they do not conduct electricity in their aqueous solutions. Hence, they are considered not to exhibit acidic behaviour. 

It is clear that alcohol and glucose are hydrogen atoms but cannot dissociate its hydrogen into hydrogen ion (H⁺).

Hence, the correct option is (B).

An acid is a substance that dissociates in aqueous solution, releasing the hydrogen ion H⁺ (a proton):

$HA\rightleftharpoons A^{-}+H^{+}$

Whenever an acid is dissociated in water it always gives H⁺ ion. 

So, the acidic property is due to the presence of H⁺ ion. 

Hence, the correct option is (C).

In the liquid solutions electricity is conducted by the ions. So, To conduct electricity we must require the compounds which can be dissociated into their ions. 

Since, Glucose and ethyl alcohol do not dissociate into their ions in aqueous solution so will not conduct electricity. 

HCl is a strong acid so it is dissociated into H⁺ ion and Cl^- ion in their aqueous solution. So, they can conduct electricity in to their aqueous solution. 

Hence, the correct option is (B).

Egg shells are made almost entirely of calcium carbonate (CaCO₃).

And when strong acids (HCl, H₂SO₄) react with crushed egg shell (calcium carbonate), it leads to the production of carbon dioxide (CO₂)^-.

$2HCl+CaC{O}_3\to CaC{l}_2 +H_{2}O+C{O}_2$

Products formed are - calcium chloride, water and carbon dioxide.

Carbon dioxide in turn when reacted with lime water (a solution of Ca(OH)₂) will cause white precipitate of calcium carbonate (CaCO₃).

So, it is clear from the above explanation that strong acids are responsible for the production of carbon dioxide which turn lime water into milky white.

Hence, the correct option is (C).
