The infection of different concentration chitosan - acetic acid solution surface sizing to the technical feature of paper was studied.
Acid number of lubricating oil can be obtained by neutralizing standard acid solution and alkalinity substance of aqueous phase.
The luminescence decay and time - resolved luminescence spectra of the excited uranyl ion in perchloric acid solution have been studied with a pulsed nitrogen laser and boxcar integrated averager.
In the form of a water solution or as litmus paper, it is the oldest and most-used indicator of whether a substance is an acid or a Base. It turns red or pink in acid solutions and Blue or purple-Blue in alkaline solutions.
(histology) not easily decolorized by acid solutions; pertains to micro-organisms (especially the tubercle bacillus that causes tuberculosis).
A waterborne multicolor paint is prepared by chitosan in acetic acid solution, mixing with short fiber and crosslinked by glutaric dialdehyde.
After de-acetylating chitin, chitosan can be easily dissolved in a dilute acetic acid solution, and chitosan fibers can b e made by extruding the solution into a dilute alkali solution.
An acid solution is concentrated when it has very much acid in it.
Counter etch: A weak acid solution ,e.g. acetic acid, used to clean a plate chemically before coating.
Acid number of lubricating oil can obtained neutralizing standard acid solution and alkalinity substance of aqueous phase.
