Sodium nitrate - Wikipedia

Sodium nitrate is the chemical compound with the formula Na N O 3.This alkali metal nitrate salt is also known as Chile saltpeter (large deposits of which were historically mined in Chile) to distinguish it from ordinary saltpeter, potassium nitrate.The mineral form is also known as nitratine, nitratite or soda niter.. Sodium nitrate is a white deliquescent solid very soluble in water.

Wastewater Treatment through Low Cost Adsorption

Apr 07, 2016· 1.1. Introduction. One of the two major environmental problems concerning the management of liquids in mining and mining-related activities, particularly relevant to a country like Chile, is the natural generation of acidic mine drainages (AMD) or acidic rock drainages (ARD) produced by chemical and/or microbial oxidation of sulphides in the presence of air and water [1, 2].

Electrolytic Cells - Purdue University

The potential required to oxidize Cl-ions to Cl 2 is -1.36 volts and the potential needed to reduce Na + ions to sodium metal is -2.71 volts. The battery used to drive this reaction must therefore have a potential of at least 4.07 volts. This example explains why the process is called electrolysis.The suffix -lysis comes from the Greek stem meaning to loosen or split up.

A Study of the Uptake of Cu2+ by Calcium Silie by Batch

rainfall. A pumping station or gate system may be added but this increases the overall cost. Hence this is not the most desirable system. When the ore is roasted in the furnace a gas stream is generated containing mainly SO. 2. and suspended solid particles rich in copper, arsenic and other metal ions. This gas

Three Ways to Prepare Nitric Acid - Owlion

Feb 04, 2019· The simplist and most used preparation of nitric acid in the lab is by adding concentrated sulfuric acid to a dry nitrate salt, usually, potassium or sodium nitrate. This mixture is heated to melt the pasty mixture and distill the nitric acid. The nitric acid that is collected is usually 95% or higher concentration and a strongly fuming liquid.

when calcium metal is added to water the gas evolved does

Jun 06, 2012· Hannah John, added an answer, on 31/7/14. Hannah John answered this. When calcium is added to water, the heat evolved is not sufficient for the metal to ch fire.But when the gas evolved reacts with the sodium metal, an exothermic reaction takes place (Because water reacts violently with Sodium metal). Here so much of heat is produced that the evolved hydrogen immediately ches fire.

Chemical or Scientific Names of Common Substances

Acid Rain - Department of Chemistry

Natural Acidity of Rainwater. Pure water has a pH of 7.0 (neutral); however, natural, unpolluted rainwater actually has a pH of about 5.6 (acidic).[Recall from Experiment 1 that pH is a measure of the hydrogen ion (H +) concentration.]The acidity of rainwater comes from the natural presence of three substances (CO 2, NO, and SO 2) found in the troposphere (the lowest layer of the atmosphere).
