Using Titration and stoichometry, what are the calculations to make 0.1M (100mL) of naOH from both...
if you make up a solution of 100mL of 0.1M HEPES in the basic form, what will be the pH?
I want to make a solution that will have [HCOO - ] = 3[HCOOH]. I start with 100ml of a 0.1M HCOOH solution. How many ml of a 1M KOH solution should I add? 5ml 7.5ml 25ml 75ml
1. How many grams of pure, solid NaOH are required to make 400 mL of 0.1M NaOH solution? 2. How many grams of a solution that is 50% by weight NaOH is required to make 400 mL of 0.1M NaOH solution? 3. The density of a 50% solution of NaOH is 1.525 g/mL. What volume of a solution that is 50% by weight NaOH is required to make 300 mL of 0.1M NaOH solution? 4. Why does weighing by difference...
Q1: In part A you will prepare a dilution solution of 0.1M NaOH using a 500mL graduated cylinder and pump dispenser. The solution is then mixed and stored in the amber bottle found in your drawer. Be sure the cap is in good condition. Calculate the volume of 6.0M NaOH needed to make 450 mL of about 0.7 M NaOH. Do not include units in answer. Q2: After the first trial, in order to maximize the titration precision, the sample...

what is the pH of a titration if 12.5 mL of 0.0500 M NaOH solution is added to 40.00 mL of 0.100 M solution of nitrous acid (HNO2) Ka=6.0 x 10-4?
For a titration experiment: I am using 1.025 M of NaOH(aq) as my titrant. My titration solution is 4.0 g of potassium hydrogen tartrate, with 300 mL of distilled water. After 4 trials, my average NaOH used was 1.680 mL. I am having problems figuring out how to calculate my findings. Each trial started with 50 mL of potassium hydrogen tartrate solution, and 2 drops of phenophthalein. Then I added 1.680 mL of NaOH (on average) to get titration to...
Titration of a Weak Monoprotic Acid with a Strong Base Volume of Base (mL) 1. Using the graph, determine the K, of the weak acid. 2. Suppose 100mL of the monoprotic acid referred to in the graph was titrated with 1M NaOH, determine the molarity of the weak acid. The corresponding balanced chemical equation is shown below. HA + NaOH + H2O + A + Nat 3. If the weak acid above was prepared by using 5g of the weak...

1. A comic book villain is holding you at gun point and is making you drink a sample of acid. She gives you a beaker with 100ml of a strong acid with pH=5. She also gives you a beaker of a strong base with a pH=10. You can add as much of the strong base to the strong acid as you want, and you must then drink the solution. You'd be best off trying to make the solution neutral before...
