SOLVED: A student is titrating ethanoic acid against sodium hydroxide, using phenolphthalein as the indicator. The student carries out three (3) titrations; all of which look like Figure 1at the endpoint:Figure 1. Titration result(a) State the error that the student has made and identify whether it is gross, systematic or random error: [2 marks](b) What effect will this error have on the final result of this titration? Briefly and clearly explain your answer: [6 marks](c) How could the student h

SOLVED: In this titration, what is the color change of the phenolphthalein indicator? b) Explain why the mean titre should be based only on titrations 2, 3, and 4.Calculate the mean titre in cm? Answer questions d) (i)-(v).Using your answer to (c), calculate the number of moles of sodium hydroxide in the mean titre.(ii) Hence, state the number of moles of ethanoic acid, CH3COOH, in 25.0 cm3 of the diluted solution used in the titration.(iii) Calculate the concentration of the diluted acid soluti
