15 Facts on HCl + AgOH: What, How to Balance & FAQs

HCl + AgOH is a chemical reaction. Let us look at this reaction’s different characteristics in detail.

 This is the reaction between strong acid (i.e., HCL ) and a weak base (i.e., AgOH).

This article will inspect HCl +AgOH products, intermolecular forces, reaction type, and its conjugate pairs.

What is the product of HCl and AgOH?

Being a strong acid HCl can completely ionize into the aqueous medium to form cations and anions.

HCl (aq) = H+ (aq)+ Cl (aq)

Silver hydroxide is a weak base so a certain amount of the molecules can dissociate into the aqueous medium.

AgOH(s)= Ag+(aq) + OH(aq)

Therefore the products formed during the reaction between HCl and AgOH are;

2AgOH + 2HCl = 2H2 + O2 + 2AgCl

What type of reaction is HCl + AgOH

The reaction of HCl and AgOH comes under a double displacement reaction. Double displacement reactions are when the anions and cations of two compounds get exchanged to form another two compounds. The formed compound AgCl is insoluble, so it’s a double displacement precipitation reaction.

How to balance HCl + AgOH

First, we must count the type of atoms in reactants and products. Then, we have to add several atoms /molecules of the compound in Infront of the formula. In this reaction, an equimolar amount of hydrochloric acid and silver hydroxide reacted to form an equimolar amount of water molecule and silver chloride.

HCl + AgOH = AgCl + H2O

HCl + AgOH titration

Apparatus Used

Burette, pipette, 250 ml conical flask, measuring jar, Burette Stand.

The indicator used

Methyl orange indicator used during the titration of strong acid v/s weak base. An endpoint is red to orange and then to yellow.


In strong acid v/s weak base titration, both base and acid react to form an acidic solution. The conjugate acid formed during titration reacts with water and forms hydronium ions. So this results in a solution with a lower than 7-PH value.

HCl + AgOH net ionic equation

The following steps can determine the net ionic equation:

  • Should write the balanced equation  first

  HCl + AgOH = AgCl + H2O

  • Naming the states of each compound

  HCl(aq) + AgOH(aq) = AgCl(ppt) + H2O (liq)

  • Split the compounds into soluble ions; this gives a complete ionic equation and cancels out the spectator ions on both sides.

  H+ + Cl + Ag+ + OH = Ag+ +Cl + H2O

  • The left-over substances can be written as net ionic equation reactions.

  H+ + OH = H20

This chemical equation is the net ionic equation for HCl and AgOH reaction.

HCl +AgOH conjugate pairs

Conjugate acid-base pair is defined as those compounds that can have the ability to accept and donate proton atoms, and they differ by one proton atom. HCl is an acid. Its conjugate base is Cl. And OH is a base its conjugate acid is H2O.

HCl and AgOH intermolecular forces

  • In HCl, there are two types of intermolecular forces between hydrogen and chloride ions: dipole-dipole interactions and London dispersion intermolecular forces. Out of these two, dipole-dipole interactions are very strong.
  • In silver hydroxide, ion-dipole interactions are present, but it is very weak compared to the silver-hydroxide bond.

HCl + AgOH reaction enthalpy

The enthalpy of the final reaction of HCl and AgOH is -351.95KJ. We can find this enthalpy by subtracting the enthalpy of products from the enthalpy of products. Therefore, enthalpy of the final reaction is= ( -167.16+105.58) -(-127.7-285.83) =-351.95KJ

Is HCl + AgOH a buffer solution

The reaction of HCl and AgOH cannot form a buffer solution because HCl, a strong acid, dissociates into ions completely. This strong acid reacts with a weak base, forming silver chloride (precipitate) and water. But the weak base and its conjugate acid can act as a buffer solution.

Is HCl + AgOH a complete reaction

HCL + AgOH is not a complete reaction. In the reaction of hydrochloric acid with silver hydroxide precipitate is formed so that its solubility product quotient is less than the solubility product constant. Hence, the residue further reacts with an excess of solid until solubility equilibrium attain.

Is HCl + AgOH an exothermic or endothermic reaction

HCl + AgOH is an exothermic reaction. Since it is a precipitation reaction, its entropy is less than zero, so from Gibbs energy equation Gibb’s energy is negative, which indicates that it is an exothermic reaction.

Is HCl + AgOH a redox reaction

HCl + AgOH is not a redox reaction since, being a precipitation reaction, only hydrogen ions transfer takes place between the reactants but not involving in the change of oxidation state of one or more reactants.

Is HCl + AgOH a precipitation reaction

HCl + AgOH is a precipitation reaction since silver chloride is formed as a precipitate, indicating that it is a precipitation reaction. Precipitation reaction is described as “the reaction which is takes place in aqueous medium giving ions; these ions further combined to form insoluble salt”.

Is HCl + AgOH reversible or irreversible reaction

The HCl + AgOH reaction is irreversible because the energy required to reverse the forward reaction is disallowed. But AgOH alone can be considered as an reversible reaction because of its partial dissociation in aqueous medium.

Is HCl + AgOH displacement reaction

HCl + AgOH is a double displacement reaction because the exchange of ions takes place here. Here positive and negative ions of both HCl and AgOH are exchanged together to form a new compound. This double displacement reaction mostly takes place in the aqueous phase.


In this article, we tried to learn about some of the properties during the reaction of HCl and AgOH. The formed silver chloride has its vast application in the preparation of electrodes in electrochemistry.
