Furthermore, when an acidic substance loses a proton, it forms a base, called the conjugate base of the acid. When a basic substance gains a proton, it forms an acid called the conjugate acid of a base. Examples
Can you think of a cause for the flavour difference? What do they usually consist of? Almost everything you use every day, whether food or soap, is an acid or a base. Neutral substances, on the other hand, are chemicals that are neither acidic nor basic in nature. Let’s take a ...
to accept a pair of electrons. They will grab an electron pair from any substance added to the solution and corrode the substance. Corrosiveness is a characteristic of acids. Thus, due to the higher concentration of hydrogen ions than that of the hydroxyl ions, the solution becomes acidic. ...
This understanding of Arrhenius' idea of acids and bases evolved through time to be articulated as follows: An acid is a substance that raises the H+ ion concentration when dissolved in water. A base is a substance that raises the OH− ion concentration when dissolved in water....
An indicator is defined as a substance that gives a visible sign, usually by a colour change, of the presence of an acid or a base in a solution. Indicators show different characteristics like colour and odour in acidic and basic mediums. Ostwald developed a theory of acid-base indicators ...
A buffer solution is a solution that shows a minor change in the value of pH when an acid or a base is added to it for dilution. Buffer solutions have various applications for industrial purposes. Answer and Explanation:1 The two components of the acidic buffer...

Broader definitions of an acid, to include substances that exhibit typical acidic behaviour as pure compounds or when dissolved in solvents other than water, are given by theBrønsted–Lowry theoryand theLewis theory. Examples of nonaqueous acids are sulfur trioxide, aluminum chloride, and boron ...
Acidic salts are formed from the neutralization of a strong acid and a weak base. When dissolved in water, the cation of the weak base reacts with water and the anion of the strong acid does not, forming an acidic solution, such as NH4Cl. What is an example of acidic salt? One exampl...
Ampholytes are amphoteric molecules that exist primarily aszwitterionsover a givenpH rangeand have both acidic groups and basic groups. Here are some examples of amphoterism: Metal oxides or hydroxides are amphoteric. Whether a metal compound acts as an acid or a base depends on the oxide oxida...
