Baking Powder ? Bicarb ?

[Claire121]

Is UK Baking Powder the same as Bicarb ? I have run out of bicarb but have baking powder and want to up my PH.

I have mixed it with tank water in a cup but it is fizzy..........

It depends, baking powder normally has an acid added to it, where as Sodium Hydrogen Carbonate (bicarb) is just that NaHCO[sub]3[/sub], look on the ingredients and see what it says.

I have three pots of baking powder to choose from !!! (hate baking...)

Dr Oetker : rice flour, sodium bicarbonate.

Tesco : disodium phosphate, sodium bicarbonate, rice flour.

Dr Oetker double action : disodium diphosphate, sodium bicarbonate, monocalcium phosphate, maize starch.

Any of these any good ?

Thanks

Non of these are suitable, they all contain starch.

You want baking SODA!


Baking powder contains baking soda, but it is not pure sodium bicarbonate.

Arm and Hammer Pure Baking Soda

To raise the KH without raising the GH, add sodium bicarbonate (NaHCO[sub]3[/sub]), commonly known as baking soda. 1/2 teaspoon per 100 Liters raises the KH by about 1 dH. Sodium bicarbonate drives the pH towards an equilibrium value of 8.2.
