What is the pH of a solution in which OH equals 6.9 x 10 -10?
4.84
OH- of a solution which has a pH equals 10.95?
pH + pOH = 14. So pOH = 14 - 10.95 = 3.05 pOH = -log[OH-] [OH-] = 8.91 x 10-4 M
What is 4N NaOH?
The atomic weight of Na-OH is 23+16+1= 40. So to prepare the one N solution of Na-OH, you need to add 40 grams of Na-OH in one litre of water. To prepare the 4N Na-OH solution, you need to add 160 grams of Na-OH in one litre of water.
Which solution are acidic assume all solutions are at 25C Kw equals 1.0 x 10-14 at 25C?
A solution with H+ = 1.2 x 10-4 a solution with OH- = 2.5 x 10 -9 A solution with pH = 4.5
Saturated solution of calcium hydroxide is added to a solution of magnesium chloride?
2(OH) + Mg ------> Mg(OH)2
Which of these solutions are acidic a solution with OH equals 2.5 10-9 H plus equals 1.2 10 -4 H plus equals 3.4 10-8 pH equals 4.5 OH equals 1.0 10-4?
solution with [OH-] = 2.5 x 10-9 , A solution with [H+] = 1.2 x 10-4, A solution with pH = 4.5

What happens when a base dissolve?
It increases the concentration of OH - in a solution.
OMG equals what?
Oh my gollywogs
Is the concentration of H plus in solution given the OH equals 2.54 x 10-4?
[H+] = Kw / [OH-] = 1.0*10-14 / 2.5*10-4 = 4.0*10-11 mol/L
What is the pH of a solution withOH equals 1 10-4?
-log[1 X 10^-4 M OH(-)] = 4 14 - 4 = 10 pH ----------------
Saturated solution of calcium hydroxide is added to a solution of magnesium chloride?
2(OH) + Mg ------> Mg(OH)2
Is a substance with equal numbers of H ions of OH - ions an alkaline solution?
No. If the number of H+ and OH- ions are equal then the solution is neutral. A solution is considered alkaline if it has more OH- ions than H+ ions.
A base produces what in a solution?
A base in solution will produce hydroxide or OH- ions.
