1. What is the molarity of a solution of NaOH if 23.4 mL
required to neutralize 25 mL of 0.25M H2SO4?
2.What is the pH of a solution produced by dissolving 1.5g HCI
to make 1L of solution?
Please help, step by step solutions .. thanks!
Using the above sodium hydroxide solution, 27.21 mL of the NaOH
solution is required to neutralize a volume of 28.45 mL of an
acetic acid solution having an unknown concentration to a
phenolphthalein end point. Determine the concentration, in
molarity, of the acidic solution. Start with a balanced
equation.
13. A 15.0 mL NaOH solution is required to neutralize
10.0 mL of 0.100 M H2SO4(aq)
solution.
What is the concentration
of NaOH solution used?
2NaOH (aq) + H2SO4(aq) → Na2SO4(aq) +
2H2O(l)
What volume (in liters) of 0.1000 M
NaOH is required to neutralize 25.00 mL of 0.0700
M
H3PO4
I am not sure how to set this problem up, I kind of have an idea
but I lost also
Suppose it took 17.38 mL of 0.098 M NAOH solution to neutralize
the acid solution and that you used 0.77 g of green crystals to
prepare the original 50.0 mL solution (of which only 10.00 mL is
analyzed for Co at a time). Calculate the mass of cobalt in the
sample, the percent cobalt and the percent error. Thank you!
What volume of a 0.153 M sodium
hydroxide solution is required to neutralize
23.2 mL of a 0.112 M
hydrobromic acid solution?
mL sodium hydroxide
B. What volume of a
0.116 M hydroiodic acid solution
is required to neutralize 19.4 mL of a
0.177 M barium hydroxide
solution?
mL hydroiodic acid
1/ Calculate the volume of 0.280-M NaOH
solution needed to completely neutralize 27.4 mL
of a 0.560-M solution of the
monoprotic acid HBr.
2/ To determine the molar mass of an organic acid, HA, we
titrate 1.047 g of HA with standardized NaOH.
Calculate the molar mass of HA assuming the acid reacts with
37.17 mL of 0.469 M NaOH
according to the equation
HA(aq) + NaOH(aq) → NaA(aq) + H2O(ℓ)
3/
2 NaBH4(aq) + H2SO4(aq) → 2
H2(g) +...
