A metal oxide may react with an acid to form a salt and water; e.g., calcium oxide reacts with carbonic acid to form calcium carbonate and water.
Chemical Pretreatment For RO and NF
Calcium and Magnesium is removed using pretreatment such as lime-soda softening and filtration, prior to feeding the RO. Weak acid ion ion exchange is used to remove hardness associated with alkalinity. Hydrogen ions released in the ion exchange reaction react with alkalinity to form carbonic acid for subsequent removal in the degasifier.

The 6 Corrosive Components That Can Be Found in Crude Oil
May 01, 2017· One of the ways to mitigate the effects of hydrochloric acid is by adding ammonium (NH 3) as a basic material to neutralize HCl.Ammonium can react with HCl to form ammonium chloride (NH 4 Cl). This substance is highly hygroscopic and can even react with water vapor (steam). The water containing NH 4 Cl is very corrosive for copper-based alloys, such as brass and bronze.
What happens when acid reacts with limestone? | Questions
Jun 15, 2008· Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks don''t dissolve very quickly. But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3- ions, which are very soluble in water, and the limestone will dissolve. Or, if there is more acid, two hydrogen ions will
Silicic Acid: Properties, Reactions and Uses | Life Persona
He Silicic acid , Is a hydrated form of silicon oxide.It is the general name for the family of chemical compounds formed by a silicon, and a certain amount of molecules of hydrogen and oxygen. The general formula for these acids is [SiO X (OH) 4-2x ] N , And the most common form in which is usually found is in the Orthosilicic acid H 4 SiO 4 .
Acid Mine Drainage: Chemistry
Nov 10, 2004· Acid Mine Drainage: Chemistry Acid mine drainage impacts stream and river ecosystems through acidity, ferric ion (Fe 3+) precipitation, oxygen depletion, and release of heavy metals associated with coal and metal mining, such as aluminum (Al 3+), zinc (Zn 2+), and manganese (Mn 2+).. When mineral deposits that contain sulfides are mined, they have the potential to produce acid …
Cleaning Badly Tarnished Brass, Bronze and Silver
Mixing acetic acid (vinegar) and sodium bicarbonate gives you aqueous sodium acetate and carbonic acid. Carbonic acid again reacts with calcium carbonate to form the much more soluble calcium bicarbonate. In this case the whole system is a lot more complex, as it contains a variety of compounds in different concentrations. The essence is that i
EDTA – Water Technology Report
Apr 27, 2015· Ethylenediaminetetraacetic acid (EDTA) reacts with calcium, magnesium, iron and copper such that precipitation does not occur. It also reacts to a lesser extent with boiler metal surfaces and may remove some magnetite, hence overfeeding of chelants should be avoided. Four (4) parts of EDTA are required per ppm metal ion.
CALCIUM CARBONATE-CARBONIC ACID EQUILIBRIUM
Most important are calcium salts (salts of the carbonic acid): •calcium bicarbonate Ca(HCO 3), which only exists in aqueous solution, •calcium carbonate CaCO 3, not very soluble (approximately 15 mg/l for T=25 °C and 25 mg/l for T= 100 °C). Other elements, especially sodium …
How is calcium bicarbonate formed - Answers
Calcium bicarbonate is usually formed when calcium carbonate (CaCO3) reacts with carbonic acid (H2CO3). CaCO3 + H2CO3 --> Ca(HCO3)2 Calcium bicarbonate can only exist in …
7.8A: Amphoteric Behavior - Chemistry LibreTexts
Calcium oxide reacts with water to produce a basic solution of calcium hydroxide, whereas carbon dioxide reacts with water to produce a solution of carbonic acid. There is a gradual transition from basic oxides to acidic oxides from the lower left to the upper right in the periodic table.
NCEA Level 1 Science/Properties and changes of matter
Oct 14, 2018· Hydrochloric acid (HCl) Sulphuric acid (H 2 SO 4) Hydrogen Chloride (HCl) is an acid because it dissolves in water to give a solution of hydrogen ions and chloride ions known as hydrochloric acid. A clue to whether a substance is an acid is whether its formula begins with H, as in HCl and H 2 SO 4. However, this is not true in all cases.
