Testing My pH Test Strips

I used vinegar, and a mix of water and baking powder to test the litmus paper test strips I have.

there are "short range" strips that can test a narrower band of PH, for instance 0.5-5.0 in 0.5 increments.

If the accuracy is to .5 or so, you are doing fine for most applications.

I have the same strips they are basically "ebay strips" and nothing will make them turn that military green color for 8 and nine. They make brighter greens so the chart is useless after about 6. also light passing through the strips changes the color or if put on a dark vs light surface.

Considering the paper is yellow to begin with, this does not look good. The ph strips I have are two dots on a white strip, I think that might be more accurate. The yellow may putting a caste to the color. Good video anyway, helped me a lot, thumbs up.

Would you recommend those cause I need to have pH papers but I am not sure which one to buy
