uestion 1 Which of the following are TRUE about using a buret? Choose all that apply The volume of liquid in the buret is read from top to bottom L. The initial volume of liquid in a buret is a smaller number than the final volume after a titration. 0 Your eye should be level with the meniscus when reading the buret A buret should always be filled to the top Question 2 How many milit ers of 0 200 M NaOH will be required to trate 16 2 mL of 0 479 M H2504 ers of 0 200 M NaOH will be required to titrate 16 2 mL of 0 479 M H2504? Do not include units and write answer to 3 significant figuresExplanation / Answer
Q1) 2and 3 point are correct
Q2) mL(acid) x N(acid) = mL(base)x N(base)
oh, and 2M for NaOH is the same as 2N.
.479M for sulfuric, however, is 0.958N.
so the eq. is: (mL(acid) x N(acid))/N(base) = mL(base)
plugging in:
(0.958N x 16.2mL)/0.200 N = 77.59 mL of 0.200N NaOH
3) water and salt
In a typical acid base neutralization the salt is created by the positive ion from the base and the negative ion from the acid forming the salt and the hydrogen from the acid combining with the hydroxide from the base to form water
4) ans is 0.00650375M
