20.0 cm3 of a H2C2O4 solution required 8.60 cm³ of a 0.2010 M solution of sodium hydroxide for complete neutralization using phenolphthalein indicator (first permanent pink end-point). 20.0 cm3 of the same H2C2O4 solution required 7.85 cm³ of a KMnO4 solution to reach the permanent pink endpoint. Calculate the molarity of both the H2C2O4 solution and KMNO4 solution.

10.06 cm³ of the stock 0.100 mol dm-3 solution of NaOH was required to fully neutralise 49.5 mg of a diprotic acid (H2A). Write a balanced equation for this reaction and hence determine the molar mass (Mr) of the acid.
Consider the spectrophotometric pH measurement of seawater with the indicator thymol blue illustrated at the opening of this chapter. The blue form of the indicator In22 on page 202 has maximum absorbance at a wavelength of 596 nm (nanometers). The yellow form HIn2 has maximum absorbance at 435 nm. Measurements of absorbance at the two wavelengths allows us to find the ratio [In22]/[HIn2]. How would you use this measurement to find the pH?
