Chemistry 1 Final Exam Review – Definition Notes

Florida Atlantic University

General Chemistry 1 (CHM 2045)

three states of matter

SOLUTION X IS 10 PERCENT ALCOHOL BY VOLUME, AND SOLUTION Y IS 30 PERCENT ALCOHOL BY
VOLUME. HOW MANY MILLILITERS OF SOLUTION Y MUST BE ADDED TO 200 MILLILITERS OF SOLUTION X
TO CREATE A SOLUTION THAT IS 25 PERCENT ALCOHOL BY VOLUME?
draw it out. 10% of 200 ml is 20 ml. So 20 ml alchohol and 180 ml water. then solution y is .3(30%) k
alcohol and .7k ml water. total solution y is k ml. New solution is 180 + .7k ml and 20 + .3k ml and total
volume is 200 + k ml.
so you have an equation: 1/4 (25%) = 20 + .3k / 200 + k. Solve for K to get 600.
strong electrolytes
Substance that dissociates completely into its ions when added to water and conducts electricity well.
weak electrolytes
produce relatively few ions when dissolved in water, weak acids, weak bases
nonelectrolytes
