Three solutions of Triblu indicator, all of equal concentration, were made at pH 1, pH 6 and pH 10. The pH 1 solution had an absorbance at 620 nm of 0.202, while the pH 10 solution had an absorbance of 0.489. If Triblu indicator has a pka of 5.0, what would the absorbance of the pH 6 solution be at 620 nm? Answer to three decimal places.

An impure sample containing carbonate and sodium bicarbonate, weighing 0.5 g, was taken. It was dissolved in distilled water and then flushed with 0.1 N hydrochloric acid. If the burette reading at the end point of the phenolphthalein index is 10.5 milliliters, and at the orange methyl index end point it is equal to 30.1 milliliters. So, the percentage of sodium bicarbonate in the sample is ............., knowing that the molecular weight of sodium bicarbonate is 84 g/mol.
