Acids and Alkalis Salts made from an Acid and a Base. Metal oxides are bases.A base will neutralise an acid. If the metal oxide dissolves in water it forms hydroxide ions and is called an alkali. Any chloride or sulfate can be safely made by reacting the correct metal oxide with hydrochloric acid …
Phosphoric acid (H 3 PO 4) has three hydrogen atoms, all of which are replaceable by a metal. Tricalcium phosphate, in which all three of the hydrogen atoms are replaced by calcium, must be converted to the soluble form, monocalcium phosphate, in which only one hydrogen atom is replaced by calcium.

Acids, Bases and Salts Acids - Acids are compounds which give hydrogen ion in water solution. For example, Hydrochloric acid (HCl), Sulphuric acid(H 2SO 4), Nitric acid(HNO 3). HCl(aq) H +Cl (Hydrogen ion) H + H O + + H O 2 3 (Hydronium ion)
A method and apparatus for recovering calcium sulfate di-hydrate (gypsum) from a precipitation reaction between cement kiln dust and commercial, spent or waste grade sulfuric acid solution. The gypsum recovered from this process acts as a necessary functional
Sulfuric acid is used in the production of phosphate fertilizers such as monoammonium phosphate, diammonium phosphate, calcium dihyrogen phosphate, and others. According to the Food and Agriculture Organization (FAO), global demand for phosphate fertilizers in 2017 was 43.2 million tons.
CaF 2 (Calcium fluoride)+ H 2 SO 4 (Conc. Sulphuric acid) → CaSO 4 (Calcium sulphate) + 2HF (Hydrogen floride) Concentrated Sulphuric acid is an intense dehydrating agent. This property is utilized as a part of drying many wet gasses that don''t react with the acid.
Sulphur trioxide, SO 3, will react with water, but the exothermic nature of the reaction means it generates a mist of sulphuric acid, which is more difficult to work with than a liquid. Consequently the SO 3 is absorbed in 98% sulphuric acid, producing oleum, and water is added to this to generate sulphuric acid.
Hydrofluoric acid is a solution of hydrogen fluoride (HF) in water.It is used to make most fluorine-containing compounds; examples include the commonly used pharmaceutical antidepressant mediion fluoxetine (Prozac) and the material PTFE (Teflon). Elemental fluorine is produced from it. is …
Sulphuric(VI) acid is very important to our daily lives. In this essay, four aspects of sulphuric(VI) acid, including its production, chemical properties, physical properties and uses will be discussed. Basic information of sulphuric(VI) acid The formula of sulphuric(VI) acid is H2SO4. It is named because the oxidation state of sulphur is +6. The diagram below …
Sulphuric acid is used in the manufacturing process of such drugs. Metal Processing: It is widely used in metal processing for example in the manufacture of copper and the manufacture of zinc and in cleaning the surface of steel sheet, known as ‘pickling’, prior to it …
Formula: Metal + Acid → Salt + Hydrogen Reactive metals give out electrons easily to form positive ions. Example: Magnesium Ribbon with Dilute sulphuric acid. …
In general, any metal with a negative reduction potential will react with any Brønsted acid (one that produces protons), no matter whether it is a weak (e.g., acetic) or strong acid (e.g., hydrochloric). And if a metal has a positive reduction potential, it won''t react

Molality of sulphuric acid is 8.01m and its density is 1.354g/ml. Find molarity and mole fraction of sulphuric acid? asked by Snehal bhoir on Deceer 23, 2017 Chemistry Iron(III) oxide reacts with carbon monoxide gas to form solid iron metal and carbon dioxide
Carbon dioxide is formed when dilute hydrochloric acid reacts with a metal carbonate (or metal hydrogen carbonate) producing effervescence. Since, one of the compounds formed during this reaction is calcium chloride, it means the metal compound is calcium carbonate (It cannot be calcium hydrogen carbonate because calcium hydrogen carbonate is found only in solution, it is also unstable to
