Why are tin granules used instead of just a piece of tin?

2 answers:

The reason why Tin granules is mostly used or preferred than just a piece of Tin because a piece of Tin is plainly metal, in which this will be difficult in having it to be oxidized when it is exposed or in the air rather than Tin granules.

Answer:

To increase the surface area of reaction.

Explanation:

The tiny granules are used as they increase the surface-area to volume ratio. Smaller granules have a higher surface area to volume ratio. In a chemical reaction, it means that the reaction increases as there is more particle to particle reaction.

Hence the granules are preferred to solids.

Andreas93 [3]

Answer:

For a: The chemical equation for the dissolution of sodium carbonate is $Na_2CO_3(s)\rightarrow Na_2CO_3(aq.)$

For b: The net acid-base reaction is $CO_3^{2-}(aq.)+H_2O(l)\rightarrow OH^-(aq.)+HCO_3^-(aq.)$

Explanation:

For a:

Dissolution reaction is defined as the reaction in which a solid compound gets dissolved in water to form aqueous solution.

The chemical equation for the dissolution of sodium carbonate follows:

$Na_2CO_3(s)\rightarrow Na_2CO_3(aq.)$

Ionization reaction is defined as the reaction in which an ionic compound dissociates into its ions when dissolved in aqueous solution.

The chemical equation for the ionization of sodium carbonate follows:

$Na_2CO_3(aq.)\rightarrow 2Na^+(aq.)+CO_3^{3-}(aq.)$

For b:

Now, the anion formed which is $CO_3^{2-}$ reacts with water to form conjugate acid.

The chemical equation for the reaction of anion with water follows:

$CO_3^{2-}(aq.)+H_2O(l)\rightarrow OH^-(aq.)+HCO_3^-(aq.)$

Hence, the net acid-base reaction of the anion formed and water is written above.
