Acid Attack on Concrete - Effects & Results of Acid …
Nitric acid attack is a typical acidic corrosion for shrinkage of the corroded layer due to leaching of highly soluble calcium nitrate. Such volume contractions of the corroded layer, especially for the case of nitric acid, can result in the formation of visually observable cracks across the corroded layer.

Magnesium rapidly dissolves in dilute sulphuric acid to give a clear colourless solution. Calcium only reacts slowly with dilute sulphuric acid to give a cloudy solution. Magnesium oxide and magnesium carbonate are similar white powders which are slightly soluble in
Calcium in biology - Wikipedia
Calcium ions (Ca 2+) contribute to the physiology and biochemistry of organisms cell.They play an important role in signal transduction pathways, where they act as a second messenger, in neurotransmitter release from neurons, in contraction of all muscle cell types, and in fertilization.

Oxyacid - Carbonic acid and carbonate salts | Britannica
Oxyacid - Oxyacid - Carbonic acid and carbonate salts: Carbonic acid (H2CO3) is formed in small amounts when its anhydride, carbon dioxide (CO2), dissolves in water. CO2 + H2O ⇌ H2CO3 The predominant species are simply loosely hydrated CO2 molecules. Carbonic acid can be considered to be a diprotic acid from which two series of salts can be formed—namely, hydrogen carbonates, …
How can I determine metal concentration in ug/g
In your case, the concentration of calcium is 7.39 ppm. It means 7.39 mg/1000 ml. So, now you can easily convert this into micro grams/g. if your sample volume is 1000 ml, amount of calcium is 7

1. Metal M on treating with an HNO3, form the nitrate salt along with the evolution of colourless, odourless gas Y. Identify the metal M and gas evolved Y. a. X= Al and Y = O2 gas b. Dear Student, All the metals do not react with nitric acid to evolve H 2 gas, as nitric acid is a strong oxidising agent,it oxidises hydrogen gas to water, and itself gets reduced to nitrogen oxides like N 2 O, NO
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.
