Asolution of household vinegar is to be analyzed. a pipet is used to measure out 10 ml of the vinegar which is placed in a 250ml volumetric flask. distilled water is added until the total volume of solution is 250 ml portion of the diluted solution is measured out with a pipet and titrated with a standard solution of sodium hydroxide. the neutralization reaction is as follows: hc2h3o2 (aq) + oh- (aq) --> c2h3o2- (aq) + h2o (l)it is found that 16.7 ml of 0.0500 m naoh is needed to titrate 25.0 ml of the diluted vinegar. calculate the molarity of the diluted vinegar.

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1

If you add 5.00 ml of 0.100 m sodium hydroxide to 50.0 ml of acetate buffer that is 0.100 m in both acetic acid and sodium acetate, what is the ph of the resulting solution? acetic acid: ka = 1.8. x 10-5

Count the number of each type of atom in the equation below, and then balance the equation. write in the numbers of atoms and coefficients. add a 1 if there should be no coefficient. cs2(l) + o2(g) → co2(g) + so2(g) c [ ] s [ ] o > c [ ] s [ ] o [ ] cs2(l) + [ ] o2(g) > [ ] co2(g) + [ ] so2(g)
