The sodium hydroxide, calcium carbonate and potassium oxide are examples of bases. A base is a material that interacts with hydrogen ions and can neutralize the acid. Bases are classified as acceptors of a proton (H+), and ammonium hydroxide are typical examples of the bases. Q4.

An acid-base reaction is a chemical reaction that occurs between an acid and a base that are the reactants. The products of this reaction are salt and water. An acid-base reaction is a double-replacement reaction where ions exchange their positions. This type of reaction is essential in both biochemistry and industrial chemistry [1,2]. General Equa...
A strong acid is one that readily gives off hydronium (H+) ions when dissolved in water (H2O). A strong base is one that quickly gives off hydroxyl (OH–) ions when dissolved in water. The H+ and OH– combine to form H2O. Strong acid and base react completely and neutralize each other. Hence, the acid-base reaction is also called neutralization react...
To determine whether a substance is an acid or base, count the hydrogens before and after the reaction. If the number of hydrogens has decreased, that substance is the acid because it donates hydrogen ions. If the number of hydrogens has increased, that substance is the base since it accepts hydrogen ions.
In most acid-base reactions, there will always be water and salts. For example, hydrochloric acid (HCl) reacts with sodium hydroxide (NaOH) to form sodium chloride (NaCl) salt and water (H2O). HCl (aq.) + NaOH (aq.) → NaCl (aq.) + H2O (l)
To balance a reaction, we must make sure that there is an equal number of atoms of a particular element on both sides of the equation. Consider the example of the reaction between phosphoric acid (H3PO4) and calcium hydroxide Ca(OH)2 resulting in insoluble Ca3(PO4)2 and water (H2O). H3PO4 (aq.) + Ca(OH)2 (aq.) → Ca3(PO4)2 (s) + H2O (l) This equatio...
Most acid-base reactions occur between strong acids and bases, resulting in complete neutralization. Below are some examples, along with the formula of the compounds . 1. Sulfuric acid (H2SO4) and potassium hydroxide (KOH) react to form potassium sulfate (K2SO4) and water (H2O). H2SO4 (aq.) + 2 KOH (aq.) → K2SO4 (aq.) + 2 H2O (l) 1. Ammonia (NH3) d...
Acid-base reactions are also observed in organic chemistry. According to Brønsted-Lowry theory, a compound that donates a proton is an acid, and a compound that accepts a proton is a base [5,6]. Example 1. Methanol (CH3OH) reacts with sodium hydride (NaH), producing the sodium salt of methanol (CH3O–Na+) and hydrogen gas (H2). CH3OH (aq.) + NaH (aq...
Complete neutralization does not occur when a weak acid reacts with an equivalent amount of a weak base. The concentrations of the species in equilibrium with each other will depend on the equilibrium constant, Ka, for the reaction. The general equation can be represented as: AH + B ⇌ A– +BH+ Example 1. Acetic acid (CH3COOH) gives off proton (H+) a...
Acid-base reactions are significant in everyday life. 1. Calciumoxide (CaO) is used to neutralize acidic soil. 2. Hydrochloric acid (HCl) in the stomach plays a vital role in digesting food. Antacids, which are bases, are taken to neutralize excess stomach acid, to prevent damage to the intestines. 3. Alkaline calcium hydroxide (limewater) is used ...

Bases have properties that mostly contrast with those of acids. Aqueous solutions of bases are also electrolytes. Bases can be either strong or weak, just as acids can.
Acids react with bases to produce a salt compound and water. When equal moles of an acid and a base are combined, the acid is neutralized by the base. The products of this reaction are an ionic compound, which is labeled as a salt, and water.
Essentially, a Brønsted–Lowry acid–base reaction involves the transfer of a proton from an acid to a base, leaving behind the original bonding electrons. Another example of an acid–base reaction is the reaction of ammonia with water: \[\mathrm{NH}_{3}(aq)+\mathrm{H}_{2} \mathrm{O}(l) \rightleftarrows \mathrm{NH}_{4}^{+}(aq ...
Acid-base reaction, a type of chemical process in which one or more hydrogen ions are exchanged between species that may be neutral (molecules, such as water or acetic acid), or electrically charged (ions, such as ammonium, carbonate, or hydroxide).
