What is the volume of NaOH needed to reach the equivalence point?

A mole is equal to 6.022 x 1023 molecules.) By doing the titration and making a plot of the volume of NaOH added versus the resulting pH of the solution, we find that the equivalence point occurs at 0.04398 L of NaOH.

What volume of the NaOH solution is required to reach the endpoint of the titration?

23.72 mL
To reach the endpoint required 23.72 mL of the NaOH. Calculate the molarity of the HCl. Put on your CHEMICAL SPLASH-PROOF SAFETY GOGGLES!

What is the volume of NaOH?

volume of NaOH = 20.0 cm 3 = 20.0 ÷ 1000 = 0.020 dm.

How does the volume of NaOH AQ NaOH AQ needed to reach the equivalence point change?

How does the volume of NaOH(aq) needed to reach the equivalence point change? The volume of added base needed to reach the equivalence point increases.

What volume of 0.250 M NaOH would need to be added to reach the equivalence point?

Answer and Explanation: Answer: 50 mL of the base NaOH is required to reach the equivalence point.

What volume of 0.100 M NaOH is needed to reach the equivalence point with 25.00 mL of 0.200 M HCl?

ANSWER: The volume of NaOH required is 25.2 mL.

How do you find the volume of a NaOH solution?

Calculating a volume

1. 25.00 cm 3 of 0.300 mol/dm 3 sodium hydroxide solution is exactly neutralised by 0.100 mol/dm 3 sulfuric acid.
2. Volume of sodium hydroxide solution = 25.0 ÷ 1000 = 0.0250 dm 3
3. Amount of sodium hydroxide = concentration × volume.
4. Amount of sodium hydroxide = 0.300 mol/dm 3 × 0.0250 dm 3
5. = 0.00750 mol.

How much 1.00 m NaOH is needed to neutralize the H 2 SO 4 solution?

From this you can see that it takes 2 moles NaOH per 1mole H2SO4.

Why is the pH of NaOH 7 at equivalance point?

There’s quite a bit of leeway because the pH changes a lot if you add even a little excess acid or base. But let’s titrate using acetic acid (HAc) weak acid, and NaOH, strong base. At the equivalance point the pH will be way above 7 because HAc- ions are themselves weak bases.

How do you titrate H2SO4 with NaOH?

These have 2 equivalent points – one when the first H+ is lost, and another when the second H+ is lost. If you are to told to titrate H2SO4 with NaOH, you can’t do it until you are told which equivalence point you are after. Then you choose a suitable indicator – one whose end point is the same as the equivalence point.

Is NaOH a good base to titrate acetic acid?

NaOH isn’t a particularly strong base. It’s not particularly dangerous either. Especially not if you use it at 0.1 M – 1M concentrations which is what undergrads use to titrate acetic acid. And no, I don’t think there is. If you use a carbonate base, you have a problem because you can’t really standardize it.

Why is the pH of an acid above 7 at equivalance?

At the equivalance point the pH will be way above 7 because HAc- ions are themselves weak bases. And what about dibasic acids? These have 2 equivalent points – one when the first H+ is lost, and another when the second H+ is lost.
