A dilute aqueous solution of PtCl4 is a pale yellow to colorless, but a concentrated solution is a deep red. What explanation can you give for this behavior? Hydrogen chloride can be prepared by heating NaCl with concentrated sulfuric acid. Why is...
For purification, the hydrogen chloride gas is passed through two zones series-connected together and scrubbed in countercurrent fashion. More particularly, it is scrubbed in the first zone with concentrated hydrochloric acid and in the second zone with concentrated sulfuric acid.[US4678482A]HAINTSU ...
A powerful method for analyzing EO or derivatized nonvolatile molecules at lower concentrations and providing a great depth of information is coupling chromatography to MS via gas chromatography-mass spectrometry (GC–MS). This method has higher sensitivity, selectivity, and structural determination capabi...
Extensions of the pyrogallol treatment diminished the velocity until it eventually became practically identical with that resulting from the use of pure hydrogen. It was, however, felt that even freshly prepared pyrogallol might possibly lead to a contamination of the gases with traces of carbon ...
In the Experimental Procedure: Yeast Fermentation, the gas bubble got larger. What gas was causing this increase in bubble size? is it carbon dioxide or ethanol? How do you neutralize an acetic acid solution? What substance has an equal number of hydrogen ions and hydroxide ions?
The tested dyes changed color in a way that is dependent and proportional to the concentration of the gas as measured using spectroscopic methods. In between the precision of a spectrometer and the human eye is the possibility of usingsmart phonesto read out and quantify the color changes or ...
With this equation, explain why the electrolysis of concentrated sodium chloride solution might be expected to release chlorine gas rather than oxygen gas at the anode. A galvanic cell is made of a Cd electrode in a 1.0 M Cd(NO3)2 solution and a...
Chromatography is a technique used to separate components of a mixture analyte and can quantify them. Gas chromatography focuses on analytes in solutions that are converted to gases upon analysis. These analytes are volatile compounds that are easily converted into gaseous state....
For the reaction, calculate how many moles of the product form when 2.65 mol of oxygen gas completely reacts. Assume that there is more than enough of the other reactant. 2 H 2 ( g ) + O 2 ( g ) 2 H 2 O ( l ) Phosphoric acid, H_3PO_4, can ...
the ICCP anode may be disposed in the anode chamber, but away from the ionic membrane to aid in preventing gas bubbles from collecting on the ionic membrane and interfering with the electroplating process. In some embodiments, the ICCP anode is in contact with the anolyte somewhere in an anoly...
