4. This reaction is used during titration in which the concentration of an acid or base in a solution is determined with the endpoint being typically indicated by a pH indicator or pH meter. 5. Sodium hydroxide is also commonly used to swell fibers and improve dye absorption during the produ...
I will speculate that it would require a very good pH meter and possibly an autotitrator using a weaker titrant than what you are using. Boric has 3 inflection points that might be hard to find. Impossible with a rapid titration or normal 1.0N sodium hydroxide. James Watts - Navarre, FL ...
The use of a sulfuric rather than a hydrochloric acid medium for the reduction of As(V) to As(III) by iodide is proposed. Optimum conditions of acid concentration, amount of sodium hydroxide, and time and temperature are established to achieve quantitative reduction. The optimized reduction ...

156 A student determines the concentration of dilute sulfuric acid, H,SOn(aq), by titrating it with aqueous sodium hydroxide, NaOH(aq).The student:transfers 10.0 cm3 of 0.100 mol/dm3 NaOH(aq) into a flask adds a few drops of methyl orange indicator to the flask fills a burette with H2...
The leachate and drainage/runoff from the storage area are collected and purified; sodium sulfate in the solution is then split into sodium hydroxide and sulfuric acid using bipolar-membrane electrodialysis. Finally, the sodium hydroxide is used in a Bayer refinery and the sulfuric acid is used ...

Why is it necessary to dilute car battery acid before titration? 1. What is the purpose of sulfuric acid or phosphoric acid used in the acetylation reaction? Use equations to explain this purpose. 2. The procedure calls for cautious addition of water to th...

Discontinuous flow analysis was applied to the determination of sulfuric acid in metallurgical process samples by photometric titration using a bromophenol blue indicator. Over-estimation of the level of acid due to the precipitation of metal hydroxides and oxides was prevented by titrating with sodium ...
