Webalkalinity present is due to HCO3- ions and can be detected by using methyl orange as indicator. 2. When P=M/2, this implies that only CO32- ions are present. Neutralization using phenolphthalein as indicator reaches upto HCO3- stage. Same amount of acid will be further used when methyl orange is used as indicator to neutralize HCO3- to H 2 O ... WebVisible absorbance spectra were obtained (Thermo Scientific Evolution 201 Spectrophotometer) for crystal violet, methyl orange, and phenolphthalein solutions at various concentrations, and five-point calibration curves were determined by comparing peak absorbance wavelength of the solution to its concentration. Anionic copolymer was …

WebI've read that phenolphthalein changes color when the pH is from above the range of 8.3 to 10.0 Conclusions: 1: Using it we have the change in color when we have more OH- than those used to neutralize the strong acid. 2: As the range is from 8.3 to 10.0, we would have an error margin of about 2 decimal points in the total concentration of H+ • WebThe indicator used in this experiment is phenolphthalein and methyl orange. Phenolphthalein, an organic compound, is colourless in acidic solution and pink in basic solution. This experiment involved acid-base standardization procedures. Standardization of the molarity of a sodium hydroxide solution (NaOH) will be determined by titrating a ... goodbaby lightweight stroller
