You have 659.3 mL of a stock solution 4.660 M HCl. For a particular experiment, your lab partner prepared a diluted solution for you to use. In her notes, you read: " Using a volumetric pipet, took 246.54 mL of stock solution and diluted it to 739.21 ml in a volumetric flask. Then, took 100.00 mL of that solution and diluted it to 194.63 mL in a second volumetric flask. " What is the concentration that you should report for...

A selection of commercial fruit juices and fruit extracts were analysed for ascorbic acid content. A student took kiwifruit juice to analyse. This juice is reputed to have ascorbic acid concentrations about 3 times greater than that of orange juice. The student diluted the juice by taking a 25.00 mL sample to a final volume of 100.0 mL. The student analysed 25.00 mL aliquots of the diluted juice solution for ascorbic acid by titration using a standardised iodine solution. Data:...

It's a weak acid strong base titration
Experiment 4: Identification of an unknown acid by titration Page 2 of 15 Background In this experiment, you will use both qualitative and quantitative properties to determine an unknown acid's identity and concentration. To do this analysis, you will perform a titration of your unknown acid sample-specifically a potentiometric titration where you use a pH meter and record pH values during the titration, combined with a visual titration using a color indi- cator...

Experiment 7, Analysis of KHP by titration with NaOH Wright College, Department of Physical Science and Engineering In this experiment, you will determine the amount (percent) of potassium hydrogen phthalate (KHP) that is in an impure sample. You will determine the percent of KHP via titration using NOH with known inolarity. The reaction will follow, KHCgH00, (aq) + NaOH (aq) ---------> KNaCHO, (aq) + H20 (I) At the end point, the...
