Hello there! I’m currently stuck on this next part od my lab. I’m struggling with the equations. Pleaae help! Thank you.
this is the concentrate of NaOH
DATA – PART 1 Write the balanced chemical equation for the reaction of HC with NaOH in the space below. NaOH + HCI – NACIT H2O Trial 4 In the table below, and asterisk (*) means e calculated quantity Trial Trial 2 Trial 3 Volume of HCl(aq) used (mL) (Diluted Toilet 10.00i 10.00ml 10.0om! Bowl Cleaner) Burette Reading: Initial Volume of 0.00ml 6.74ml 0.16ml NaOH (mL) Burette Reading: Final Volume of 26.78m1 33.75m) 27.22m! NaOH (mL) *Volume NaOH 26.78m1 27.01m1 27.06ml consumed (mL) *Moles of NaOH consumed (mol NaOH) *Moles HCI reacted (mol HCI) *Molarity of the diluted HCI solution (mol HCIL) *Average molarity of the diluted HCI solution *Molarity of the original HCI solution Show the calculations on the next page as required.
Show one set of calculations for the determination of the molarity of the diluted HCI solution Show your calculation for the determination of the average molarity of the diluted HCI solution. Show the calculation for the determination of the molarity of the original HCl solution (Toilet Bowl Cleaner) from the molarity of the diluted solution. 149
Rinse a burette with deionized water and then with the 0.1000 M NaOH(aq), as instructed. Clamp the rinsed burette to the ring stand and completely fill it with the NaOH(aq) solution. Add enough to go above the scale. Briefly open the stopcock wide open to force any bubbles out of the tip, and to ensure the complete filling of the bottom of the burette. Once this is complete, record the initial volume of NaOH(aq) in your burette to the proper number of significant figures.
