Acids and Bases
nitric acid and the mixture of nitric and hydrochloric acids, which was called aqua regia,"kingly water," because of its ability to dissolve the noble metal gold. Sulfuric acid was discovered in the 10th century. In the 17th century, atomists tried to explain chemical
Casein - an overview | ScienceDirect Topics
As the isoelectric point of caseins is approximately 4.6, addition of acid (lactic, hydrochloric or sulphuric) to milk also results in casein micelle destabilisation and precipitation of the caseins. Caseins manufactured in this manner are washed and neutralised with sodium, potassium, ammonium or calcium hydroxides to between pH 6.8 and 7.2 ( Modler, 1985 ).

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.
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
Oxidation-Reduction (Redox) Reactions
When zinc metal is submerged into a quantity of aqueous HCl, the following reaction occurs (Figure 5.4 "Zinc Metal plus Hydrochloric Acid"):Zn(s) + 2HCl(aq) → H 2 (g) + ZnCl 2 (aq) This is one example of what is sometimes called a single replacement reaction because Zn replaces H in coination with Cl.

Lab 10 - Solubility Product for Calcium Hydroxide
The concentration of Ca(OH) 2 (s) does not appear in the equilibrium constant expression because it is always present as the pure solid (activity is 1), no matter how much or how little of it is present. A saturated solution of Ca(OH) 2 can be prepared by the reaction of calcium metal with water.

2016/1/14· Here''s one method. In this reaction, phosphoric acid, "H"_3"PO"_4, a weak acid, will react with calcium hydroxide, "Ca"("OH")_2, a strong base, to produce calcium phosphate, "Ca"_3("PO"_4)_2, an insoluble salt, and water. Since you''re dealing with the reaction between a weak acid and a strong base, you can say that this is a neutralization reaction. Judging from the products of the reaction
What Are the Effects of Sulfuric Acid on Metal? - wiseGEEK
2020/8/6· The effects of sulfuric acid on metal depend on a nuer of factors, including the type of metal, the concentration of the acid, and the temperature. Dilute sulfuric acid will, in theory, react with any metal that lies above hydrogen in the reactivity series by displacing hydrogen from the acid, releasing it as a gas and forming the sulfate salt of the metal.
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.[2] HClO cannot be isolated from these solutions due to rapid equilibration with its precursor
