For example, hydrochloric acid, HCl, is a strong acid. HCl(aq) → H + (aq) + Cl − (aq) A strong base is one that is fully dissociated in aqueous solution. For example, sodium hydroxide, NaOH, is a strong base. NaOH(aq) → Na + (aq) + OH − (aq) Therefore, when a strong acid reacts with a strong base the neutralization reaction can be ...
A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and chemical formulas.The reactant entities are given on the left-hand side and the product entities are on the right-hand side with a plus sign between the entities in both the reactants and the products, and an arrow that points towards the products to show the direction of the reaction.

Hydrochloric acid is a strong inorganic acid that is used in many industrial processes such as refining metal. The application often determines the required product quality. [25] Hydrogen chloride, not hydrochloric acid, is used more widely in industrial organic chemistry, e.g. for vinyl chloride and dichloroethane. [8]
The reaction with hydrochloric acid is an equilibrium reaction that favors formation of tetrachloroaurate(III) anions. This results in a removal of gold ions from solution and allows further oxidation of gold to take place. The gold dissolves to become chloroauric acid. In addition, gold may be dissolved by the chlorine present in aqua regia ...
Crystal structure of calcite. Calcium carbonate is a chemical compound with the chemical formula Ca CO 3.It is a common substance found in rocks as the minerals calcite and aragonite, most notably in chalk and limestone, eggshells, gastropod shells, shellfish skeletons and pearls.
Social Security is the U.S. government's biggest program; as of June 30, 2024, about 67.9 million people, or one in five Americans, collected Social Security benefits. This year, we're seeing a...
The key to cooking juicy chicken without a spit in this healthy recipe is high heat and dark meat. The yogurt in the marinade gives the chicken both its tender texture and its alluring char. More ...
The reaction between hydrochloric acid and calcium carbonate (limestone or chalk) is shown below: CaCO 3 + 2 HCl → CaCl 2 + H 2 CO 3. The carbonic acid (H 2 CO 3) then decomposes to water and CO 2: H 2 CO 3 → CO 2 + H 2 O. Such reactions are accompanied by foaming or bubbling, or both, as the gas is released.
