a) i. A suitable indicator for the titration of a strong acid (H_2SO_4) with a weak base (Na_2CO_3) is one that changes color in the acidic pH range. Methyl orange ii. State the colour of your chosen indicator: I. In the base: Yellow II. At the end point during titration: Orange iii. Why was the indicator used? The indicator was used to visually determine the end point of the titration. Methyl orange is suitable because its color change range (pH 3.1-4.4) matches the acidic pH at which the equivalence point of a strong acid-weak base titration occurs. Send me the next one 📸
