i did .1 mols of AC- + .1 mols of OH gives me .2 mols of AC. the .2 mols of AC reacts with water AC- + H20---> OH- + HAC so the M is .2/.05 L = 4M to solve for the OH conc i did X^2 / 4 = 5.6 x 10^-10. and solving for the pH i get 9.675 is this right?
What is the pH of a solution prepared by adding 4.000 grams of NaOH to a 50.00 mL of a buffer that is 2.00 molar both in acetic acid and sodium acetate? (Assume final volume is still 50.00 mL)
I dont think this would be correct because The solution you are proposing would have a pH over 12.
how many mL of .100 M of acetic acid and .100 M of NaOH, would be need to make the volume 1.0 liters and have a pH7.00 if Ka=1.8x10^-5 please write out the steps or eq for me im gettin stuck
37 is a and 38 is i think a and b
Yes "A" has reflective symmetry, not rotational symmetry.
The mass times the coefficient of friction
Two angles are complementary. THe sum of the measure of the first angle and one forth of the second angle is 58.5 dagrees. Find the measure of the angles.
20% of num is x. the num is 4 more than x . what's the number.
How many Ca +2 ions in 40.08g of CaCO3 (Calcium Carbonate) I'm unsure on how to approach this problem and set it up.
