what is the difference between acid and base reactions?

Strong acids react completely with water to produce H3O+(aq) (the hydronium ion), whereas weak acids dissociate only partially in water. Conversely, strong bases react completely with water to produce the hydroxide ion, whereas weak bases react only partially with water to form hydroxide ions.

General acid-base catalysis involves a molecule besides water that acts as a proton donor or acceptor during the enzymatic reaction. ... Specific acid–base catalysis means specifically, –OH or H+ accelerates the reaction.

Explanation: Acids and bases have various strengths, all depending on their pH . An extremely strong base would be more dangerous than a weak acid, and vice versa.

Bases are substances that react with acids and neutralize them. ... Alkaline solution/compound is the same as a basic solution/compound. But you can specify "alkali" to refer to those bases that are soluble in water and that are salts of alkaline or alkaline earth metals too.

An acid is a substance that produces hydrogen ion (H+) as the only positive ion when mixed with water. A base is a substance that produces hydroxyl ion (OH–) as the only negative ion when mixed with water. An acid is a species that can release/donate a proton to another species.

The main difference between acid base indicator and universal indicator is that acid base indicators show color changes at a certain pH range whereas universal indicators show color changes at a wide variety of pH values ranging from 0 to 14.

Reaction of acids and bases with metals. ... In general, bases do not react with metals and release hydrogen gas.

Acids release H+ ions that can turn neutral molecules into positively charged ions, while bases can attract H+ ions from neutral molecules to produce negatively charged ions.

Acids and bases both react with water and a lot of acids and bases are soluble in nature. Both acids and bases are electrolytes which means that they're good conductors of electricity. Acids and bases both produce ions in water solution. Acids release hydrogen ions (H+) whereas Bases release hydroxide ions (OH–).

When a hydrogen ion is released, the solution becomes acidic. When a hydroxide ion is released, the solution becomes basic. Those two special ions determine whether you are looking at an acid or a base. For example, vinegar is also called acetic acid.

The difference is minor, but there is one. Essentially a base is a chemical which will react with an acid to form a salt and water only. An alkali is a water-soluble base. ... Insoluble bases, which are not called alkalis, are all metal oxides and insoluble metal hydroxides.

Thus H + is an acid by both definitions, and OH − is a base by both definitions. Ammonia (NH 3) is a base even though it does not contain OH − ions in its formula.

The reaction of an acid with a base is called a neutralization reaction. The products of this reaction are a salt and water. ... For example, the reaction of hydrochloric acid, HCl, with sodium hydroxide, NaOH, solutions produces a solution of sodium chloride, NaCl, and some additional water molecules.

Why acid/base neutralization reactions are exothermic. The neutralization of a strong acid with a strong base is examined and found to always add heat to the surroundings.

Neutralization. A neutralization reaction is when an acid and a base react to form water and a salt and involves the combination of H+ ions and OH- ions to generate water. The neutralization of a strong acid and strong base has a pH equal to 7.

A conjugate acid contains one more H atom and one more + charge than the base that formed it. A conjugate base contains one less H atom and one more - charge than the acid that formed it.

Bases can be either water soluble or insoluble. Insoluble bases react with acids, directly dissolving in the acid as they react. ... When an acid and a base are combined, water and a salt are formed. For example, when hydrochloric acid is mixed with sodium hydroxide, water and sodium chloride are formed.
