Determine the molarity of a sodium hydroxide if 16.88 mL of the sodium hydroxide solution is required to react with 25.00 mL of 0.500 M sulfuric acid. If the titration of a 30.0 mL sample of sulfuric acid requi
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 10.0cm3 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 H2SO...
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 ...

Sodium bicarbonate is added until the fizzing of {eq}CO_2(g) {/eq} stops. If 35 ml of 6.0 M {eq}H_2SO_4 {/eq} was spilled, what is the minimum mass of {eq}NaHCO_3 {/eq} that must be added to the spill to neutralize the acid?

Amidosulfuric acid and sodium carbonate as standards for acid–base titrimetry were assayed by coulometric titration and gravimetric titration. Amidosulfuric acid was directly assayed by coulometric titration with electrogenerated hydroxide ions, and sodium carbonate was assayed by gravimetric back-titration....
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 ...
