I'm trying to read up on the chemicals and I see the % on this data sheet is for 5% but I'm guessing 12.5 is obviously stronger.

Look at page 3, section 7 under handling and storage.  7th or 8th short sentence says "Never add water to this product"  Isn't that what we will or are all doing?

Thanks,

Jeff

I take it by the face your disappointed! I'm sure I'm missing something here. No worries, I will keep reading. The good news is the local place that I can get it does carry it in the 12.5%

Now honestly, how do you and the rest of the world use SH in our laundry? Do you not think it's being mixed with water.

I realized it was a dumb question, but it was too late. I hit Post. Maybe they should set up a forum for Newbie dumb questions with a "TOP 10 LIST"

hey Jeff from Mn. Not a dumb question at all!  Science Lab says," Never  ADD water to this product."  They could have also said,It's okay to ADD the product to water.  The rule of thumb when mixing is to add the chemical to the water, not the other way around.  This is important  to follow when mixing very strong acids and very strong alkali with water. (Seems to happen more with acids.)  A violent reaction can occur and
splatter chems for several feet! 
So thanks for asking the question Jeff, you may have saved someone from some nasty chemical burns!

- add the chems to the water is only a rule of thumb.

- more importantly, read the MSDS-

Hope this was helpful.  PLAY SAFE OUT THERE!

That's a good point. They kinda' throw it out of context, they seem to imply that the two are incompatible.

NO VIOLENT REACTION OCCURS BETWEEN SH AND WATER. EVER.

STOP PROPAGATING THIS FOOLISHNESS.

He didn't say SH reacted violently with water. He's simply stating the rules of mixing. And he is correct,...you add chemical to water not the other way around. Just,.."Mixing 101"

Jeff, you must mix water with the 12.5% Sodium Hypochlorite unless you want it that strong.

He insinuated it. Anyway that aside,

 

You can even pour pure potassium hydroxide flakes into even a very small amount of water and you will not have the violent reaction that he claims. It will get instantly hot as heck but it will certainly not throw chemicals several feet. edit: and by that I mean it won't throw them any feet! Might rise a tiny bit for a second.

I am aware of Mixing 101 thank you. Just trying to clear up the silliness. I won't post in this thread again.
