A student has been asked to titrate an HCl solution with a concentration of 0.35 M against an unknown concentration of NaOH solution. He found that he used 24.35 ml of HCl in order to neutralize 36.44ml of NaOH. You are now given this information in order answer the following three questions3,4 and 5: 3- The data above refers to a titration of NaOH with a known concentration of HCl. Calculate the moles of HCl at the end point. a) 8.5 moles HCl b) 0.14 moles HCl c) 0.0096 moles HCl d) 0.0085 moles HCl e) None of the above are correct. 4- Calculate the moles of NaOH present at the end point of the titration. a) 12.8 moles NaOH b) 0.013 moles NaOH c) 0.0096 moles NaOH d) 0.0085 moles NaOH e) None of the above are correct. 5- Calculate the molarity of NaOH. a) 0.23 M NaOH b) 0.35 M NaOH c) 0.53 M NaOH d) 1.9 M NaOH e) None of the above
