Why when tested with a red litmus paper baking powder dont change the color or litmus paper?

There can be 2 questions to this answer:
Baking Powder is mainly composed of NaHCO3
When a substance which is acidic or basic in nature is dissolved in water it shows disassociation, it divides into ions. For instance HCl divides into H+ and Cl- ions. This dissociation decides the nature of a substance more concentration of H+ more is the acidity. But this disassociation of a acidic or basic substance only only takes place in water hence until and unless the baking powder is put into water it won't turn red litmus blue.
Another cause can be that you might be testing acidity or basic nature long time after putting the baking soda in water. Baking powder is not only NaHCO3 but has acidic crystals with it. So when we put in water a neutralization reaction takes place producing CO2 and H2O. After some time the basic nature could go away due to the neutralization reaction.

Why is litmus paper useful?
Water provides H+/ OH- ions for the dry gas(to be tested with litmus) to show its acidic/alkaline nature.

What is the best household powder to put in your sons play forensics kit?
I would recommend both Baking Powder and Cinnamon, because it depends on which surface you will be lifting the prints from. For my science project, I tested 7 common household powders. These are Cinnamon, Baking Powder, Maybelline Mineral Powder, Baby Powder, Coco Powder, Horse Radish and Cornstarch. I then compared all these prints to a "Master Copy" that was made using a professional black forensic powder. I also tested over 5 different surfaces. Including black tile, white Formica countertop, glass, aluminum can and plastic bottle. Aluminum can defiantly generated the most identifiable features followed by the plastic bottle.Cinnamon was the most effective powder (this was measured by the total number of features.)But, Cinnamon did extremely well on the plastic bottle and the aluminum can. It didn't do well on the glass, black tile or white Formica countertop. Baking powder received the most rounded results. It did well on four surfaces, while Cinnamon did extremely well on two surfaces.So, it really depends on the surface which powder you should use. So I recommend both Baking Powder and Cinnamon.
What color did the litmus paper turn to when you test tap water?
There are different types of Litmus paper and so the exact color may differ for each of these types. Also, water itself is neutral when pure but most tap water is slightly basic so it depends on what you use. -- Tap water will not cause any colour change when tested with litmus paper. Blue litmus paper remains blue, the same goes for red litmus paper. Although the above statement says that tap water is slightly basic, the pH is still close to neutral and will not be significant enough to cause a colour change for the litmus paper.
What factors could be tested using litmus paper?
The acidity or alkalinity of a solution, pH indicator.
