Piano World Home Page Forums Our Most Popular Forums Piano Tuner-Technicians Forum What is the chemical name of baking powder

Hello, I have seen that that powder is used to fight smells.

I have no idea on what that product is. Is is some potash, or is it somethink for the kitchen?

Or is it to make sodas ?

I am surprised as the power used to make bread or cook, is sold in very small quantities.

SO what is the chemical name, and common use ?

Thank you

Sodium bicarbonate.

NaHCO3 - (Sorry, this word processor won't do a subscript. The "3" should be little and below the "O")

It is used primarily in baking and cooking. Chemically, it is a base compound. In its dry form, it will also absorb aromas, similar to activated charcoal (carbon).

Soda, (seltzer water) is made from the gaseous infusion of carbon dioxide into water.

You are looking for Baking soda, not baking powder for smell removal...

Baking soda is NaHCO3, sodium hydrogen carbonate.

For it to work it needs an acid ingredient to release the CO2.

Baking powder is a mixture, therefore does not have a formula.

So, in baking powder there is a dry acid that is released when water is added. This can be tartaric acid from grapes or citric acid or others. And in double acting baking powder there is another carbonate that releases in the oven heat.

I think you meant baking soda. Used in refrigerators and other areas to remove smells.

Thank you so much, indeed this can be find in large quantities as well

The same product is used with hydrogen peroxyde to whiten the ivory.

I did not know it could be used as it is to "catch" the smells

I knew I could count on your precise explanations Dan

Yes it is unless you can get your hands on 40 volume peroxide.

Well I noticed there are 2 different ways to grade hydrogen peroxide , as mine is rated 130) vol. (but I know it must be +- similar to the 40 grade you state (?)

I use a little powder anyway, but not too much as it can even make craters in ivory (the best tip is to put the liquid on a paper towel laid on the keys)

I don’t use peroxide liquid I use the gelled stuff easier to control and doesn’t run all over the place.

Quick table for you Isaac:

10 vol = 3% H2O2

20 vol = 6% H2O2

30 vol = 9% H2O2

40 vol = 12% H2O2

If you want to convert volume to %

(Volume value) x 0.3 = percent

or

To convert % to volume

(% value) divided by 0.3 = volume.

How do you gel it ?

well my 130 vol is 39 % , really heavy stuff then , difficult to find and need to stay out of the light

I have read something else about 'real vol' value and commonly used designation. (?)

I suppose I don't need to use the reactive power, but it makes the process very fast (just dusting some powder on the paper towel

when the paper is dry the process is really finished, often even before. No sun or UV needed (but a good washing, plus a good sanding before buffing, the "grain" raise always a little.

I don’t gel it I purchased this from my wife’s hairdresser.

There are two kinds they use in that industry the liquid and the gelled.

This stuff is really corrosive you have to watch it; gloves and glasses for sure.

Isaac if you are adding baking soda there could be a chemical reaction; I would watch it with the gasses that come off, you could damage your lungs.

If sunlight is used not very much is required.

When it is cloudy I use a 24 inch Grow & Show full spectrum florescent tube commonly used for sprouting plant seeds.

Ah OK I get it... (while it is probably some gelatin mixed)

Yes Dan there is a "little" reaction, mostly it makes a little foam, something I take care is about the paper towel as it can ignite (no disposing it in trash can before washing)

No baking soda in the glass with peroxide, too much warmness and too much foam. no natural bristle brush neither (I did that one

I had an UV tube, it broke, possibly it is better to use a less concentrated solution plus UV, I was always instructed to use that high grade (it whiten the wood also a lot, it helped me with a keyboard that was "moistened" by the fire dept guys... and was full of brown traces on the cedar)

I stopped my grass plants when the tube broke, unfortunately

Ha! You’re funny. I expect the tube could be used for growing that sort of stuff.


Yes I suppose it could be some kind of gelatin product in the peroxide.
