This interaction may reduce the efficiency of the chemicals applied (such as a change in pH value caused by mixing alkalis and acids) and in some cases may even emit toxic fumes. An example of this is the mixing of ammonia-based cleaners (or acid-based cleaners) and bleach. [5]
The adjective alkaline, and less often, alkalescent, is commonly used in English as a synonym for basic, especially for bases soluble in water. This broad use of the term is likely to have come about because alkalis were the first bases known to obey the Arrhenius definition of a base, and they are still among the most common bases.
Acids Food acids are added to make flavors "sharper", and also act as preservatives and antioxidants. Common food acids include vinegar, citric acid, tartaric acid, malic acid, folic acid, fumaric acid, and lactic acid. Acidity regulators Acidity regulators are used to change or otherwise control the acidity and alkalinity of foods. Anticaking ...

Alkali salts or base salts are salts that are the product of incomplete neutralization of a strong base and a weak acid. Rather than being neutral (as some other salts), alkali salts are bases as their name suggests. What makes these compounds basic is that the conjugate base from the weak acid hydrolyzes to form a basic solution.
For acid-resistant building facades, such as brick, acids are typically used. These include mixtures of phosphoric and hydrofluoric acids as well as surfactants. For acid-sensitive facades such as concrete, strongly alkaline cleaners are used such as sodium hydroxide and thickeners. Both types of cleaners require a rinsing and often special ...
Nitric acid: highly corrosive and toxic strong acid; used for the production of fertilizers, production of explosives, and as a component of aqua regia, as well as mixed acid for nitration of aromatic compounds Osmium tetroxide: in organic synthesis, is widely used to oxidise alkenes to the vicinal diols Oxalyl chloride
Animation of a strong acid–strong base neutralization titration (using phenolphthalein).The equivalence point is marked in red. In chemistry, neutralization or neutralisation (see spelling differences) is a chemical reaction in which acid and a base react with an equivalent quantity of each other.
