Study of silver extraction from Ag ScienceDirect

Solvent extraction is one of the usual methods for silver extraction by using alkyl amines, ternary amine oxides, phosphines, phosphine oxides, and phosphine Silver Nitrate. In the preparation of silver nitrate dilute nitric acid is used. Silver combines with HNO3 and forms silver nitrate.Preparation and uses of Silver chloride and Silver nitrate

Studies of extractive removal of silver(I) from chloride solutions

Extraction of silver depended on concentration of hydrochloric acid, sodium chloride and extractant and additionally on the contact time.

Testing for Halide Ions Chemistry LibreTexts

Using silver nitrate solution. This test is carried out in a solution of halide ions. The solution is acidified by adding dilute nitric acid. The nitric acid reacts with, and removes, other ions that might also form precipitates with silver nitrate. Silver nitrate solution is then added, and the halide can be identified from the following products:Iron is very easily oxidised under alkaline conditions. Oxygen in the air oxidises the iron (II) hydroxide precipitate to iron (III) hydroxide especially around the top of the tube. The darkening of the precipitate comes from iron chemguide

extraction of titanium chemguide

The overall process. Titanium is extracted from its ore, rutile TiO 2. It is first converted into titanium (IV) chloride, which is then reduced to titanium using either magnesium or sodium. Conversion of TiO2 into TiCl4. The ore rutile (impure titanium (IV) oxide) is heated with chlorine and coke at a temperature of about 1000°C.What would be the probable reaction between acetone, $\ce{(CH3)2CO}$, and isopropyl alcohol, $\ce{CH3CHOHCH3}$, at room temperature without any catalyst in different concentrations?What is reaction between isopropyl alcohol and acetone?

extraction of metals introduction chemguide

Reduction by electrolysis. This is a common extraction process for the more reactive metals for example, for aluminium and metals above it in the electrochemical series. You may also come across it in other cases such as one method of extracting copper and in the purification of copper. During electrolysis, electrons are being added directlyAlkenes react in the cold with pure liquid bromine, or with a solution of bromine in an organic solvent like tetrachloromethane. The double bond breaks, and a bromine atom becomes attached to each carbon. The bromine loses its original red-brown color to give a colorless liquid. In the case of the reaction with ethene, 1,2-dibromoethane is formed.Reactions of Alkenes with Bromine Chemistry LibreTexts

iron and steel chemguide

Mild steel. Mild steel is iron containing up to about 0.25% of carbon. The presence of the carbon makes the steel stronger and harder than pure iron. The higher the percentage of carbon, the harder the steel becomes. Mild steel is used for lots of things nails, wire, car bodies, ship building, girders and bridges amongst others.For the silver halides, the solubility product is given by the expression: K sp = [Ag +(aq) ] [X -(aq)] The square brackets have their normal meaning, showing concentrations in mol dm -3. If the actual concentrations of the ions in solution produce a value less than the solubility product, you don't get a precipitate.Testing for halide ions chemguide

solubility product calculations chemguide

So the concentration of the dissolved magnesium ions is the same as the dissolved magnesium hydroxide: [Mg2+] = 1.71 x 10-4 mol dm-3. The concentration of dissolved hydroxide ions is twice that: [OH-] = 2 x 1.71 x We need a solution of halide ions. The step is adding a dilute nitric acid to acidify the solution. The nitric acid starts reacting with and removes the other ions present that might form precipitates with silver Halide Test What, Conditions, Tests & Outcome
