Which equation represents the correct net ionic equation for the reaction between Ca(OH)2 and H2SO4?

Georgia [21]

Answer: The correct net ionic equation for the reaction is $2H^{+}(aq)+2OH^{-}(aq)\rightarrow 2H_2O(l)$

Explanation:

Net ionic equation is defined as the equations in which spectator ions are not included.

Spectator ions are the ones that are present equally on the reactant and product sides. They do not participate in the reaction.

The balanced molecular equation is:

$Ca(OH)_2(aq)+H_2SO_4(aq)\rightarrow CaSO_4(aq)+2H_2O(l)$

The complete ionic equation follows:

$Ca^{2+}(aq)+2OH^-(aq)+2H^+(aq)+SO_4^{2-}(aq)\rightarrow 2Ca^{2+}(aq)+SO_4^{2-}(aq)+H_2O(l)$

As calcium and sulfate ions are present on both sides of the reaction. Thus, they are considered spectator ions.

The net ionic equation follows:

$2H^{+}(aq)+2OH^{-}(aq)\rightarrow 2H_2O(l)$

Hence, the correct net ionic equation for the reaction is $2H^{+}(aq)+2OH^{-}(aq)\rightarrow 2H_2O(l)$

Chemical reactions are only able to occur in one direction. Chemical reactions are only able to occur in one direction. True Fal

blagie [28]

Answer:

False

Explanation:

While chemical reactions can proceed in the forward direction , they can in fact also proceed in the backward direction too. The direction they would proceed depends majorly on the state of chemical equilibrium at that particular time for that particular chemical reaction.

It should be known that when a chemical reaction proceeds in the forward way, more products are formed and the reactants are used up. If however, the chemical reaction proceed in the backward way, more reactants are formed and the products are used up.

A practical example is in the case of an exothermic reaction. This is one in which heat is released to the surroundings as a result of the reactants being at a higer energy level compared to the product. Now, depending on the prevailing equilibrium constraint, the reaction could proceed forward or backward.

If for example, the temperature is decreased, this is a constraint being applied to the equilibrium state. The chemical reaction would take a shift and will favor the forward reaction and more of the products will be formed. And also of the temperature is increased, it is the backward reaction that is favored
