thank you in advance!'
Use the data in the table below to answer the next two questions. Pag question The following table shows data from the titration of four 250 ml samples of a perchloric acid solution, HCIO.(1), using a 0.225 mol/L sodium hydroxide standard solution. Bromothymol blue is used as an indicator to detect when the endpoint is reached Titration of 25.0 mL of HCIO, with 0.225 mol/l NaOH(aq) Trial 1 2 الما 3 4 19.9 19.3 38.8 final burette reading (mL) 38.4 0.4 0.2 19.9 19.3 initial burette reading (ml) volume of NaOH(aq) added (ML) blue green green green colour at endpoint
