Given three acid-base indicatorsâ€”methyl orange (end point at pH 4), bromthymol blue (end point at pH 7), and phenolphthalein (end point at pH 9)â€”which would you select for the following acid-base titrations? (a) perchloric acid with an aqueous solution of ammonia (b) nitrous acid with lithium hydroxide (c) hydrobromic acid with strontium hydroxide (d) sodium fluoride with nitric acid
Malonic acid (HO2CCH2CO2H) is a diprotic acid. In the titration of malonic acid w ith NaOH, stoichiometric points occur at pH = 3.9 and 8.8. A 25.00-mL sample of malonic acid of unknown concentration is titrated with 0.0984 M NaOH, requiring 31.50 mL of the NaOH solution to reach the phenolphthalein end point. Calculate the concentration of the initial malonic acid solution. (Sec Exercise 113.)
Suppose that you want to titrate a sample of vinegar with standard sodium hydroxide solution to determine the concentration of acetic acid in it, and you want to use an indicator to help you determine the end-point. Which of the following indicator would be suitable?

Q.1: Determination of % composition of mixture of KI & KNO3 using Eoscein as indicator.
An acid-base indicator is usually a weak acid with a characteristic color in the protonated and deprotonated forms. Because bromocresol green is an acid, it is convenient to represent its rather complex formula as HBCG. HBCG ionizes in water according to the following equation: HBCG + H2O ⇌ BCG- + H3O+ (yellow) (blue) a. Write the Ka expression for bromocresol green based on the equation above. b. When [BCG-] = [HBCG], then show that the expression simplifies to Ka = [H3O+]. If you know the pH of the solution, then the [H3O+] and Ka can be determined. c. What would be the color of the solution if there were equal concentrations of HBCG and BCG-?
Phenolphthalein (Ka = 1 x 10−9) would be a good indicator choice for the titration of a weak base with a strong acid?
