marishachu [46]

Answer:

Below is the clarification of that same particular question.

Explanation:

  • Le Chatlier's theory states that whenever an equilibrium mechanism is disrupted by environmental influences, the program responds by changing the supplies information of its constituents in a somewhat way that the disturbance is invalidated and reaches a stable equilibrium during that disrupted stage, with concentrations of stability differently than ever before.
  • Bromothymol blue seems to be a phenolic subs lone which always allows it to act throughout aqueous solutions as an acidic solution. Being such an acid (weak), it should not add to rapid, as well as introduces a balance with its accompanying but mostly disconnected form.

<u>For that kind of weak diprotic predictor, the standard economic statement can indeed be published as:</u>

    ⇒  H_2In_(aq)\rightleftharpoons In^{2-} +2H^+

  • It could be conclusively proven from either the theory of Le Charlier whereby, that whenever a strong acid becomes applied, the full disorientation of one or the other, through equilibrium formation, induces an increase throughout the medium's proton concentrations.
  • Likewise, it absorbs the protons throughout the media to split water that whenever a solution is added. So, particle concentration throughout the medium is decreasing. To accommodate for this transition, the equilibrium reacts by moving to the correct i.e. causing further dissociation of the optimistic predictor into their dianion through protons, thereby attempting to nullify that perturbation.

What is the chemical formula of the salt produced by the neutralization of potassium hydroxide with sulfuric acid? A. KSO3 B. K2
Lunna [17]

Answer : The correct option is, (C) K_2SO_4

Explanation :

Neutralization reaction : It is a type of chemical reaction in which an acid react with a base to give salt and water as a product that means it reacts to give a neutral solution.

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

When potassium hydroxide react with sulfuric acid then it react to give potassium sulfate (salt)and water as a product.

The balanced chemical reaction will be:

2KOH+H_2SO_4\rightarrow K_2SO_4+2H_2O

The species present on the left side of the right arrow is the reactant and the species present on the right side of the right arrow is the product.

In the balanced chemical reaction,

KOH and H_2SO_4 are reactants.

K_2SO_4 and H_2O are products.

Hence, the chemical formula of the salt produced by the neutralization of potassium hydroxide with sulfuric acid is, K_2SO_4
