Why 200gr sodium carbonate does not dissolve in 200ml water

 

[GDC]

Because Solubility of Sodium Carbonate: 21.4g/100ml H2O and Hydroxide not defined @ 20°C

 

[TucoSalamanca.]

Can you write the calculations of the 1st and 2nd stages? sodium carbonate

 

[TucoSalamanca.]

There is very little p2np left, can you write the full list of ingredients required for 7.5 g p2np, I have sodium carbonate but no sodium hydroxide?

 

[GDC]

Na2CO3
70g/L (0 °C)
164.0g/L (15 °C)
340.70g/L (27.8 °C)
pH=14+log(2×0.09989)=13.3006 inside 1000ml H2O
0,1 Mol Na3CO3 == ~10,6g * 50 = 530g / 245g =

2,16 L H2O with 530g Na2CO3 @ 20°C

NaOH
418 g/L (0 °C)
1000 g/L (25 °C)[
pH=14+log(0.1)=13 inside 1000ml H2O
0,1 Mol NaOH == ~4g NaOH * 50 = 200g

Sodium bicarbonate (baking soda)	0.1 N	8.4
Sodium carbonate (washing soda)	0.1 N	11.6

.

Sodium hydroxide (caustic soda)	N	14.0
Sodium hydroxide	0.1 N	13.0
Sodium hydroxide	0.01 N	12.0

I'm not sure if i'am right xD its to late and you have to check it with someone other

You want the half of the 15g P2NP:

100g NaOH 100ml H2O or 265g NaCO3 and 1,08 L H2O

But caution !!!! I think you need the double of NaCO3

 

[GDC]

Bullshit
I correct it later: https://bbgate.com/threads/synthesis-of-amphetamine-from-p2np-via-sncl2-and-zn.9878/post-53908

 

[TucoSalamanca.]

How can I tell if it's amphetamines?

 

[GDC]

Drugtest, heat some of it to the desired temperature (it will melt and burn)

 

[TucoSalamanca.]

how can I use it

 

[GDC]

Amphetamine:

• Formula C9H13N
• Molar mass 135.210 g/mol
• Density 0.936 g/cm3 at 25 °C
• Melting point 11.3 °C (52.3 °F)
• Boiling point 200-203 °C (397 °F) at 760 mmHg

What are you mean?

 

[TucoSalamanca.]

Can you write all calculations 7.5g p2np

 

[TucoSalamanca.]

I have some sodium carbonate left, should I sell it, please write the correct calculations

 

[GDC]

Yes you should, sodium carbonate produces a lot of impurity.
NaOH is much better.

7,5 g of P2NP in ~25 ml of anhydrous acetone
~25ml acetone and 21 g of tin(II) chloride dihydrate
75 ml of cold water and 2 ml 36% hydrochloric acid
sodium hydroxide (100g per 100ml of water)
3 x 25 ml portions of ethyl acetate
30 ml glacial acetic acid
5 g of zinc dust.
25 g NaOH in 50 ml water
25 ml dichloromethane
3x 10 ml DCM.
anhydrous magnesium sulfate ~1/20 of the final solution
25 ml of anhydrous acetone

 

[TucoSalamanca.]

sodium carbonate instead of sodium hydroxide

 

[TucoSalamanca.]

how much sodium carbonate how much water should be used

 

[GDC]

So sry for the last confusing post, but i will correct it now:

For the 25g NaOH inside 50ml H2O you need:

We need to calculate the molarity of the NaOH solution.
Molarity (M) = (mass of solute in grams) / (molar mass of solute) / (volume of solution in liters)
Molarity = 25 g / (39.997 g/mol) / (50 ml / 1000 ml/L)
Molarity = 0.625 M

Calculate moles of sodium hydroxide: Moles of NaOH = Molarity x Volume (L) = 0.625 M x 0.050 L = 0.03125 moles of NaOH

Calculate moles of sodium carbonate required to replace NaOH: 1 mole of NaOH requires 1.22 moles of Na2CO3.
Moles of Na2CO3 = 1.22 x Moles of NaOH = 1.22 x 0.03125 moles = 0.038125 moles of Na2CO3

Calculate mass of sodium carbonate required:
Mass of Na2CO3 = Moles of Na2CO3 x Molecular mass of Na2CO3 = 0.038125 moles x 105.9888 g/mol = 4.039 g

So, you will need 4.039 g of sodium carbonate to replace the 25 g of sodium hydroxide. You can dissolve this amount of sodium carbonate in 50 ml of water to achieve a similar concentration as the original NaOH solution.

For the 100g NaOH inside 100ml H2O you need:

Calculate molarity of NaOH solution:
Molarity (M) = (mass of solute in grams) / (molar mass of solute) / (volume of solution in liters)
Molarity = 100 g / (39.997 g/mol) / (100 ml / 1000 ml/L)
Molarity = 2.501 M

Calculate moles of sodium hydroxide:
Moles of NaOH = Molarity x Volume (L) = 2.501 M x 0.100 L = 0.250 moles of NaOH

Calculate moles of sodium carbonate required to replace NaOH:
1 mole of NaOH requires 1.22 moles of Na2CO3.
Moles of Na2CO3 = 1.22 x Moles of NaOH = 1.22 x 0.250 moles = 0.305 moles of Na2CO3

Calculate mass of sodium carbonate required:
Mass of Na2CO3 = Moles of Na2CO3 x Molecular mass of Na2CO3 = 0.305 moles x 105.9888 g/mol = 32.30 g

So, you will need 32.30 g of sodium carbonate to replace the 100 g of sodium hydroxide. You can dissolve this amount of sodium carbonate in 100 ml of water to achieve a similar concentration as the original NaOH solution.

I hope you enjoyed my answer an LIKE it

Sodium hydroxide (NaOH) is a stronger base than sodium carbonate (Na2CO3).
This is because sodium hydroxide completely dissociates in water, releasing hydroxide ions (OH-), which are responsible for its basic properties:
NaOH → Na+ + OH-
On the other hand, sodium carbonate also dissociates in water but forms a weak acid (carbonic acid, H2CO3) and a weaker base (hydrogen carbonate ion, HCO3-) compared to NaOH:
Na2CO3 + H2O → H2CO3 + 2Na+ + 2OH-
H2CO3 → H+ + HCO3-
The weaker basicity of sodium carbonate compared to sodium hydroxide means that solutions of sodium carbonate will have a lower pH and milder basic properties than solutions of sodium hydroxide at the same concentration. Therefore, sodium hydroxide is considered a stronger base than sodium carbonate.

 

[TucoSalamanca.]

I don't know molar calculation, can you tell me directly how many grams of sodium carbonate will dissolve in how many ml of water? 2 alkali calculation

 

[TucoSalamanca.]

I can't afford sodium hydroxide.

 

[GDC]

4.039 g of sodium carbonate to replace the 25 g of sodium hydroxide. You can dissolve this amount of sodium carbonate in 50 ml of water to achieve a similar concentration as the original NaOH solution.

32.30 g of sodium carbonate to replace the 100 g of sodium hydroxide. You can dissolve this amount of sodium carbonate in 100 ml of water to achieve a similar concentration as the original NaOH solution.

So:
7,5 g of P2NP in ~25 ml of anhydrous acetone
~25ml acetone and 21 g of tin(II) chloride dihydrate
75 ml of cold water and 2 ml 36% hydrochloric acid
Na2CO3 (32,30g per 100ml of water)
3 x 25 ml portions of ethyl acetate
30 ml glacial acetic acid
5 g of zinc dust.
4,039 g Na2CO3 in 50 ml water
25 ml dichloromethane
3x 10 ml DCM.
anhydrous magnesium sulfate ~1/20 of the final solution
25 ml of anhydrous acetone

 

[hacke8]

Thank you for your answer. This damn translator always makes us wrong. What kind of reagent is GAA? Glacial acetic acid?

Hello, it is said that there is an extraction procedure. EA here is used as extractant (solvent) for extraction of oxime.
