4.9_Redox_Titration__and_Stoichiometry__FRQ (1)

I need help with one of my pre-lab questions which I want to understand. Its question number 2, the one that highlighted. I don't want to make it over-complicated, I want something that I can understand.

I need help on questions 2-8?

Number two plz

In the titration of NaOH with vinegar, a student overshot the endpoint (i.e. added too much NaOH solution). How will this affect the calculate percent acetic acid in the vinegar? percent will be too high percent will be too low no effect on the percent ding of this buret? 21 Click Save and Submit to save and submit, Click Save All Answers to save all answers.

Please help

The addition of water to an aqueous solution will result in (______) volume and (____)  concentration.

Please answer fast i give you upvote.

THE QUESTION IS AT THE PICTURE... 2 QUESTIONS ONLY.. AND THE GIVEN PROBLEMS IS THE ONE I TYPED........ATTACHED PHOTO IS MY ANSWER BUT PLEASE CORRECT ME IF I AM WRONGA. Concentration1. Place 3 mL each of 6N, 3N, & 1.5N hydrochloric acid in separate test tubes.2. Drop simultaneously equal lengths (about 1cm) of magnesium ribbon and note thetime it takes for the magnesium to dissolve in each use.B. Surface Area1. Weigh a small iron nail to the nearest hundredths of a gram and weigh an equalamount of iron fillings.2. Place them in a separate test tubes.3. Add simultaneously 3 mL of 3N hydrochloric acid and compare the rates of reaction.C. Temperature1. Place 5 mL each of 0.1N sodium thiosulfate solution into 5 test tubes.2. Place all five test tubes in the water bath and let it stand for 1 minute.3. Record the temperature of the water bath. Remove the first test tube from thewater bath and place it in the test tube rack.4. Add 1 mL of 0.1M sulfuric acid and stir with a glass rod.…

i) How many moles of hydrochloric acid were there in the volume of acid added in the titration? ii) How many moles of calcium hydroxide were there in the 25 cm sample of solution that the student used in the titration? iii) What was the concentration of the calcium hydroxide solution in mol/dm?

For each of the following scenarios, determine if the error will cause the molarity of the hydrochloric acid to be greater than, less than, or the same as the initial value. A: A student adds 50 mL of water to the reaction flask with unknown hydrochloric acid instead of the 25 mL sated in the procedure. B: A student adds 50 mL of water to the reaction flask with unknown hydrochloric acid instead of the 25 mL stated in the procedure. C: A student doesn't notice the some of the HCL has dripped out from the volumetric pipet when transferring to the reaction flask

Can you please please please not reject this question. I really need to know this. AND THIS IS NOT A GRADED QUESTION.  So can someone please answer this without rejecting this everytime. I really need to learn how to do the calculations for this becuse I have my exam within 2 weeks. So please someone and this is not a graded question. Okay this time I have included all the information. Molarity is included.  An experiment was conducted by following the procedure below.   Prepare a 50-mL burette for titration. Rinse the clean burette and tip with two 5-mL portions of standardized 0.005 M HCl solution and discard. Fill the burette with standardized   HCl, remove the air bubbles in the tip, and record the initial volume (± 0.01mL).      Record the molarity of the HCl solution, which is 0.005M Cover the flask with parafilm to avoid contact with carbondioxide from air. Rinse a 25 mL pipet with 1 or 2 mL of the saturated Ca(OH)2 solution and discard. Pipet 25 mL of the filtrate into a clean…
