Solve this chemistry practical for me

Here is the solution to your chemistry practical problem. a) To find the average volume of acid used, we identify the concordant readings (those within ± 0.10 cm^3 of each other). In this case, all three readings (24.80, 24.70, 24.70) are concordant. Step 1: Calculate the average volume of acid used. Average volume of acid = 24.80 cm^3 + 24.70 cm^3 + 24.70 cm^33 Average volume of acid = 74.20 cm^33 Average volume of acid = 24.73 cm^3 b) To calculate the concentration of the acid, we use the titration formula. We assume the acid is monoprotic (e.g., HCl) and reacts with sodium hydroxide in a 1:1 molar ratio. Step 2: Calculate the concentration of the acid. Given: Volume of base (V_b) = 25.0 cm^3 Concentration of base (C_b) = 0.10 M Average volume of acid (V_a) = 24.73 cm^3 (from part a) Using the formula C_a V_a = C_b V_b: C_a = (C_b V_b)/(V_a) C_a = 0.10 M × 25.0 cm^324.73 cm^3 C_a = (2.50)/(24.73) M C_a = 0.101 M c) To find the concentration of the acid in g/dm^3, we multiply its molar concentration by its molar mass. We will assume the acid is hydrochloric acid (HCl) for this calculation. Step 3: Calculate the concentration of the acid in g/dm^3. Molar mass of HCl = 1.008 (H) + 35.453 (Cl) = 36.461 g/mol Concentration in g/dm^3 = Molar concentration × Molar mass Concentration (g/dm^3) = 0.10109 mol/dm^3 × 36.461 g/mol Concentration (g/dm^3) = 3.69 g/dm^3 d) For a strong acid-strong base titration, a suitable indicator is one that changes color around the neutral pH. Step 4: Name a suitable indicator. A suitable indicator for this titration is phenolphthalein. e) The color of phenolphthalein at the endpoint of a strong acid-strong base titration is a very faint pink. Step 5: State the color of the indicator at the end point. The color of phenolphthalein at the end point is faint pink. That's 2 down. 3 left today — send the next one.
