Caustic soda is not available for me :*(

Besides, it's pretty high on the pH scale with a pH of like... 13 so I can't randomly get it in a store :T_T:
I'm also lazy =p

But it's the Lye I'm looking for :*( I need lye with my pretzels Dx

If you can't get caustic soda then I doubt you'd be able to get the asbestos or Nafion membranes needed to separate the anode and cathode :/

You could try this:
Sodium hydroxide may be formed by the metathesis reaction between calcium hydroxide (also known as lime) and sodium carbonate (also known as soda ash):
Ca(OH)2 + Na2CO3 â†’ CaCO3 + 2 NaOH

P.S. Sodium hydroxide = Caustic soda = Lye. Same thing just different names.

Edit: Oh, Hi Infamy *waves*

Ohh yeah I know that they're the same thing, I just want to homemake some Sodium Hydroxide =D

Mmm,, I just I can take some Calcium Oxide and place it in water and for Sodium Carbonate... Arm & Hammer? XD....

damn it... I'll just buy some Lye.. Dx My crazy experiment to make lye is sad :*(

Dawwwww, I remember talking about the hydrogen now... T_T

I know that, but the question didn't give a mass number. :/ Here's the chart we had to fill out:

My answers are italicized, and I got the ones in blue correct. The red answer was wrong because I guessed and was lost on how to find the neutrons. :P

Did they say 207-Pb or something by any chance? Or gave the superscript notation? If not I can't really help you there D:. If they did say 207-Pb or something of the sort, you can find out the number of neutrons by subtracting the atomic number from the mass number, in other words 207 - 82 = 125 for this particular isotope of Pb. You could have been given 206,208,210 Pb for all we know lol .-.

As for neutral Pb, the number of neutrons doesn't matter in a neutrally charged Pb, the number of neutrons would be the same regardless. This probably didn't help much but hopefully it clarified something lol D:.

@JustNoOne

Making sodium hydroxide can be accomplished by mixing sodium oxide with water.

Na2O (s) + H2O (l) -> 2 NaOH (aq)

However, this is extremely dangerous seeing as though sodium is a very volatile metal and isn't something you should mess lightly with.

The reaction you posted before:

NaCl(aq) + H2O(l) --> Na(OH)(aq) + HCl(g)

This reaction is not possible unless you do something crazy. Crazy as in I don't know what you have to do because it proceeds in the opposite direction so spontaneously you'd have to turn back time to make the previous reaction occur D8.
