In a titration experiment with your product, it took 1.1 mL of phenylmagnesium bromide to turn the indicator from yellow to orange. What is the concentration of the phenylmagnesium bromide solution if you started with 68.5 mg of indicator? Report you answer to 3 decimal places.
Molar mass of phenylmagnesium bromide = 12*6 + 5 + 24 + 79.9 = 180.9g mol-1
mass of phenylmagnesium bromide taken = 68.5mg
volume taken = 1.1ml
Conc = 68.5*10-3 / 180.9*1.1*10-3 = 0.344M

You perform your first titration using your NaOH with a KHP solution. Your KHP solution is made with 0.5093 g of KHP. The initial amount of NaOH in your pipette is 15.43 mL and the final amount in your buret is 35.38 mL when the indicator changes color. Determine the concentration of your NaOH solution. Write your answer to four decimal places without units.
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...

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...
