A salt is an ionic compound containing positive ions other than H+ and negative ions other than OH-. Most salts will dissociate to some degree when placed in water. In many cases, ions from the salt will react with water to produce hydronium ions or hydroxide ions. Any chemical reaction in which water is one of the reactants is called a hydrolysis reaction.
Salts can be thought of as being derived from the neutralization of an acid and a base. A salt formed from a strong acid and a strong base1 will not hydrolyze (react with water). When placed in water, these salts dissociate completely, and their ions remain uncombined in solution. An example of such a salt is NaCI, formed from a strong acid (HCI) and a strong base (NaOH).
Salts formed from a strong acid and a weak base hydrolyze to form a solution that is slightly acidic. In this kind of hydrolysis, the water molecules actually react with the cation of the weak base. For example, when ammonium chloride, NH4CI, hydrolyzes, water molecules react with the NH4+ ion:
NH4+ and 2H2O yields to NH4OH and H3O+
The formation of the H30+ ion from this reaction makes the solution acidic.
Salts formed from a weak acid and a strong base hydrolyze to form a solution that is slightly basic. In this kind of hydrolysis, it is the anion of the weak acid that actually reacts with the water. For example, when sodium acetate, NaC2H3O2, hydrolyzes, water molecules react with the acetate ion:
C2H3O2- and H2O yields to HC2H3O2 and OH
The formation of the OH- ion from this reaction makes the solution basic.
Salts formed from a weak acid and a weak base produce solutions that may be slightly acidic, slightly
basic, or neutral, depending on how strongly the ions of the salt are hydrolyzed.
What else can I help you with?
What is salt hydrolysis?
Salt hydrolysis is a chemical reaction in which a salt reacts with water to produce an acid and a base through the transfer of protons between the water and the salt ions. This process occurs when salts are made up of the conjugate base of a weak acid and/or the conjugate acid of a weak base. As a result, the solution may become acidic, basic, or neutral depending on the nature of the salt and the strength of the conjugate acids and bases involved.

Name that reaction by which a chemical compound is broken down due to reaction with water?
When a compound is broken down by the reaction with water, this is termed hydrolysis.
What is meant when you say that the hydrolysis ofATP to ADP is used to drive a reaction?
The hydrolysis of ATP to ADP is used to drive a reaction in metabolism.
What is a reaction that breaks down compounds by the addition of water?
Hydrolysis is the type of reaction occurring when complex molecules are broken down into simpler ones by the addition of water.Example:Hydrolysis of a molecule of a disaccharide, such as sucrose, into two molecules of a monosaccharide, such as glucose.C12H22O11 + H2O ---> 2C6H12O6
What is hydrolysis of salts in water?
This is a "reaction" with water, a dissociation of the salt in ions.

What is another name for hydrolysis?
Another name for hydrolysis is reaction. Hydrolysis is a chemical reaction where water reacts with a compound. This produces other compounds.
Is sucrose a hydrolysis reaction or a condensation reaction?
Sucrose hydrolysis is a type of reaction where water is used to break down sucrose into its constituent monosaccharides, glucose, and fructose. It involves the addition of water to break a chemical bond. Thus, sucrose hydrolysis is a hydrolysis reaction.
What type of chemical reaction is ATP H2O - ADP Pi energy?
This reaction is a hydrolysis reaction, specifically the hydrolysis of ATP into ADP and inorganic phosphate (Pi). It releases energy stored in the high-energy bonds of ATP.
When neutralization takes place what plus water is formed?
When acid reacts with base, this reaction forms water and salt, this proccess is known as neutrilization. and the reverse reaction in which salt reacts with water to form an acid and a base is known as hydrolysis.

The reaction of NH4NO3 with water to form an acidic solution is called a oxidation b hydrolysis C electrolysis D reduction?
The reaction of NH4NO3 with water to form an acidic solution is called hydrolysis. This is because the water molecule reacts with the salt to break it down into its acidic and basic components.
