please circle the observation, write the equation and explain why the color observed
A. Determination of pH by the Use of Acid-Base Indicators Color with 0.1 M Solution of HCl NaH,PO HC,H,02 Indicator Methyl violet Thymol blue Methyl yellow Congo red Bromcresol green pH range Blae red - blue ,2S-2.2s Circle the observation(s) for each solution that was most useful in estimating the pH range. B. Measurement of the pH of Some Typical Solutions Record the pH and the color observed with bromcresol green for each of the 0.1 M solutions that were tested. NaHSO 130 NaCI Na,CO NaC,H,02 pH Color For any two solutions having a pH less than 6 or greater than 8, write a net ionic equation to explain qualita- tively why the solution has that pH. Solution NaHSo Equation lution Naa Equation Explain why the color observed with bromcresol green for each of the four solutions is reasonable, given the pH.
