Transfer 0.5 mL phenolphthalein to a flask 25 mL KHP. Then transfer 13.2mL NaOH in the KHP that make it be pink. As the picture shows. Now, show a complete calculation for the concentration of the sodium hydroxide solution.

Lemon juice contains citric acid which is tribasic(H3Y). 25cm^3 of lemon juice was diluted to 250cm^3. 25cm^3 of the solution was neutralized by 15cm^3 of 0.1M sodium hydroxide. a) Calculate; i) concentration of the diluted solution of lemon juice ii) concentration of the original lemon juice. iii) percentage by mass of citric acid in lemon juice.

Questions 11-14 refer to the same strong base/strong acid (SB/SA) titration. A 15.00 mL solution of 0.100 M sodium hydroxide (NaOH) is being titrated with 0.250 M hydrobromic acid (HBr). What is the total solution volume (in mL) at the equivalence point? (Nearest whole number)

Incorrect Your answer is incorrect. • KC: Your answer is incorrect. • Cacl, Vour answer is incorrect. For each of the following compounds, decide whether the compound's solubility in aqueous solution changes with pH. If the solubility does change, pick the pH at which you'd expect the highest solubility. You'll ind K, data in the ALEKS Data tab.
