What products would you expect from a reaction between hcl and koh?

1 answer:

8 0

HCl is a strong acid and KOH is a strong base. HCl dissociates to form H⁺ ions and Cl⁻ ions and KOH dissociates to give out K⁺ and OH⁻ ions.
When H⁺ and OH⁻ ions react they form H₂O molecules which are neutral.K⁺ ions and Cl⁻ ions form KCl salts.
the balanced equation for the reaction is as follows
HCl + KOH ----> KCl + H₂O
products are therefore KCl and H₂O

Ok another chemistry question! This is another question that I can)t solve

Hey there!

NaHCO₃

Notice that there is no subscript under Na.

That means there is one atom of Na for each molecule of NaHCO₃.

Hope this helps!

In the following reaction, identify the oxidized species, reduced species, oxidizing agent, and reducing agent. Be sure to answe

Answer :

$Cl_2$ is reduced species.

$KI$ is oxidized species.

$Cl_2$ is oxidizing agent.

$KI$ is reducing agent.

Explanation :

Redox reaction or Oxidation-reduction reaction : It is defined as the reaction in which the oxidation and reduction reaction takes place simultaneously.

Oxidation reaction : It is defined as the reaction in which a substance looses its electrons. In this, oxidation state of an element increases. Or we can say that in oxidation, the loss of electrons takes place.

Reduction reaction : It is defined as the reaction in which a substance gains electrons. In this, oxidation state of an element decreases. Or we can say that in reduction, the gain of electrons takes place.

Reducing agent : It is defined as the agent which helps the other substance to reduce and itself gets oxidized. Thus, it will undergo oxidation reaction.

Oxidizing agent : It is defined as the agent which helps the other substance to oxidize and itself gets reduced. Thus, it will undergo reduction reaction.

The balanced redox reaction is :

$Cl_2(aq)+2KI(aq)\rightarrow 2KCl(aq)+I_2(aq)$

The half oxidation-reduction reactions are:

Oxidation reaction : $2I^-\rightarrow I_2+2e^-$

Reduction reaction : $Cl_2^++2e^-\rightarrow 2Cl^-$

From this we conclude that the $'KI'$ is the reducing agent that loses an electron to another chemical species in a redox chemical reaction and itself gets oxidized and $'Cl_2'$ is the oxidizing agent that gain an electron to another chemical species in a redox chemical reaction and itself gets reduced.
