In a laboratory, thymol blue (T) will be quantified using a calibration curve. To do this, a Stock solution of thymol blue Cstock =6 10^-5 M dissolved in
1 M HCI is prepared. From this solution, 5 systems are prepared (gauged with 1 M HCI), whose absorbance is read at 455 m, obtaining the following
data:
On the other hand, 2 mL was taken from a test solution and made up to 10 mL with 1 M HCI (solution A). Of this, 3 mL were taken and
They made up to 10 mL with HCl (solution B).
