2. How many ml of 10.0M HCl do I need to add to 100ml of 1.00M NaOH to get a solution with pH = 7?
3. 75.0ml of 1.00M HCl is added to 100ml of 1.00M NaOH. what is the pH of the resulting solution?
If I can get help with these two, I can do the others. Thank you.
If 8.5 grams of solid NaC2H3O2 are added to 100.0 mL of water, how many mL of 1.0 M HCl would need to be added to prepare a solution that has pH of 4.60. ( )40.0mL ( )48.0mL ( )60.0mL ( )75.0mL
How many mL of 1M NaOH do you need to add to 300 mL of 1 M acetic acid to make a buffer with a pH of 5.46? Water will be added to bring the total volume of the buffer to 1 L. The pKa of acetic acid is 4.76.
I need to make 100mL of a 50mM HCl solution. I have a 5 M stock HCl solution. How much of my 5 M HCl solution and how much water should I add to make 100mL of a 50mM HCl solution?
Normality of HCl is 11N. Calculate how many mL of 11N HCl are needed to make 100mL of 0.1M solution.
Given: pH: 7.60 Concentration (M): 0.050 mL: 100mL Determine the Mass of Each Component Recall that buffers are formed from conjugate acid/base pairs. Using the information given about your assigned buffer, determine how much of each component (acid and base) you will need in order to prepare it in the lab. (This will require a system of equations because there are two “unknowns.”) Note: the conjugate acid in this case is H2PO4−, and the conjugate base is HPO42−. 1. Using...
i need the answer asap. i will give you a thumps up #. How many ml of a 6.00 molar NaOH solution would be needed to prepare 525 ml of a 2.5 molar solution? (Show your work and circle your answer) #. Given that 29,1 ml of 0.251 molar NaOH neutralizes a 1000 ml sample of HSo,, what is the concentration of the acid? (Hint- balance the equation before doing your calculation.) (Show your work and circle your answer.) HSO4.NOH......
c) Calculate the pH if 95 ml of 10.0M HC (ag) is added to 200.0 ml of this buffer. For full creds, show your work in detail. (4) aj Calculate the pH if 9.5 mL of 10.0 M NaOH (ag) is added to 200.0 mL ofa freshly prepared solution of this buffer. For full credit, show your work in detail (4) e) You should see from the calculations that this buffer is better able to buffer against added acid than...
10 mL of 1M NaOH solution is titrated with 0.5M HCl to a pH of 2. What volume of HCl was added? (in unit of mL) Please show all work and explain!
How many moles of HCl need to be added to 200.0 mL of a 0.200 M solution of NaF to make a buffer with a pH of 3.60? (Ka for HF is 6.8 x 10-4)
