Chapter 12.5: Acid Base Reactions - Chemistry LibreTexts
The Arrhenius Definition of Acids and Bases The first person to define acids and bases in detail was the Swedish chemist Svante Arrhenius (1859–1927; Nobel Prize in Chemistry, 1903). According to the Arrhenius definition, an acid is a substance like hydrochloric acid that dissolves in water to produce H + ions (protons; Equation 12.5.1), and a base is a substance like sodium hydroxide that

calcium carbonate plus hydrochloric acid yields calcium chloride, water (H2O), and carbon dioxide Note: When you add an active metal to water or when you react an acid with a base and produce water it makes it easier to balance the equation if you write water as HOH and treat it as hydrogen hydroxide when you balance it.
Corrosive Environments - Haynes International, Inc.

Tartaric Acid | Tradeasia International
Higher yields of calcium tartrate are obtained with the addition of calcium chloride. Calcium tartrate is then converted to tartaric acid by treating the salt with aqueous sulfuric acid. This process yields L-(+)-tartaric acid: Ca(O 2 CCH(OH)CH(OH)CO 2) + H 2 SO 4
Sulfamic Acid - an overview | ScienceDirect Topics
Sulfamic acid is useful in the removal of calcium scales but not iron oxides. A mixture of sulfamic acid and sodium chloride can remove iron oxide scale through slow generation of hydrochloric acid. Sulfamic acid can be used in cleaning equipment containing
Acid-Base Reactions | Chemistry [Master]
Acid and metal reaction: Hydrochloric acid oxidizes zinc to produce an aqueous metal salt and hydrogen gas bubbles. Recall that oxidation refers to a loss of electrons, and reduction refers to the gain of electrons. In the above redox reaction, neutral zinc is 2+ +

Hypochlorous acid - Wikipedia
Hypochlorous acid (HOCl or HClO) is a weak acid that forms when chlorine dissolves in water, and itself partially dissociates, forming hypochlorite, ClO−. HClO and ClO− are oxidizers, and the primary disinfection agents of chlorine solutions. HClO cannot be isolated from these solutions due to rapid equilibration with its precursor
