What is in B&Q's caustic soda? Well, caustic soda of course you foolish
boy! But the reason I ask is that it is labelled "concentrated caustic
soda" which makes me think it may be mixed with an inert filler. If it
was _just_ caustic soda, I'd expect it to be labelled just "caustic
soda". Any thoughts?

Water probably, pure sodium hydroxide is a solid.

I don't follow your logic though, I would expect something described
as "concentrated" to be stronger than the same thing without
"concentrated" in the description.

Would you like to buy some concentrated gold?
Only 2x the price and you can smelt it with 10x its weight of copper to
get 12x the amount of 24 carat gold.

Wouldn't that yield 2.18 carat gold?

This is solid.

I wouldn't, though I would expect it to be stronger than the same thing
called "dilute". Suppose you were buying table salt at a supermarket:
wouldn't you expect it just to be called "table salt" not "concentrated
table salt? Sugar, just "sugar", and so on? Washing up liquid might
well be called concentrated meaning that it's got less water in than
stuff not so labelled. But what has "concentrated caustic soda" (solid,
remember) got less of than just "caustic soda"?

Mind you, I might be mad.

Its probably mixed with that there dark matter the scientists are lookin
for!


Surely if its concentrated it would be in a smaller box. Perhaps it needs
some kind of preservative or knowing how it pongs, perhaps its nice spring
flowers.

bleach fr example, is a solution of IIRC sodoum hypochl;rite in water.
Concentrated bleach is IIRC teh same but with less water.

Typically caustc soda crysals are 'pure' caustic soda plus wahetever
resisue is left from the chemical process used to produce it - i.e.
about 99% plus - again I am rusty here - but I think it absorbs water
from the air etc in 'pure form' - a bit of water


IIRC again you CAN get caustc soda in solition, which is the esame
dissolved in more, or less water. And is therefore less or lesser
concentrated..

Perhaps if they are normally in the business of diluting it prior to
sale, they use "concentrated" in the sense of "full fat"

According to it's data sheet, it's 100% sodium hydroxide.

googling through some other brands sold as caustic soda, their claimed
concentration of NaOH is as low as 60%, which makes B&Q's concentrated in
comparison, although it isn't really, it's just that other companies sell
diluted stuff

You know how orange juice that is made from concentrate is
reconstituted back to 100% juice?

If it was reconstituted with less water, could it legally be sold as
(say) 110% orange juice?

Sausages are apparently allowed to contain more than 100% meat due to
some weight being lost from the ingredients during manufacture ...

Sodium chloride at a guess.

I think sodium chlorate has got a good dollop of fire retardant in it.

Just to clear that up for goodness knows who. 24 carat gold is 100% or pure, concentrated gold. he other stuff contains hardener which also dilutes it.

Actually when a fruit juice in Britain states it is made from concentrate, it means it is preserved in sugar. What concentration it is restored to is anyone's guess as they don't remove the sugar. Not unless you count diluting it with water.

It wouldn't be sensible or safe. Sodium Hydroxide can fail to dissolve in water. I am not sure of the reasons but it can also boil up all over you -which is the main reason not to use the dry stuff.

Don't get any of it on your fingers - it can do dreadful things to flesh.
If you do get any on your skin, wash it off immediately.

I'm pretty sure everyone here is aware of that, and that I was only
making a point. The weasel word "concentrated" when appearing on
packaging etc, usually means less dilute than before, and is often
accompanied by claims that this removes traffic equivalent to a dozen
2CVs from the road.

That's not something I've tried to clear with it - but I can vouch for the fact it dissolves hair - as a friend found when they borrowed a paintbrush without telling me they were about to apply sodium hydroxide paint stripper with it...
