what is the pH of the paper? is it neutral?

The package doesn't specify the exact ph, but acid free should mean the ph is 7 (neutral) or slightly above 7. Hope this helps.

I don't remember, but do your self a favor and don't buy it ! The ph litmus paper you buy at gardening centers are cheaper, more efficient and easier to use !

Most pens calibrate at 7.0, check your pH meter's instructions for further calibration information

There are 80 sheets of 80gsm acid-free, pH neutral high grade vellum paper, with light lilac dots consisting of 5mm intervals between the dots. The pages have micro-perforated paper for easy removal.

pH information provided by Nia24 on their website puts this products pH at 6.0 - 7.0. So, no, I don't think it has anything acidic in it.

pH refers to free Hydrogen ions in solution. Excess H+ ions is acidic. In water, there are very few ions. Lo ion means low ion, as in not very many to read. This is why there is a difference between saliva or urine pH papers and lo ion water pH papers. For reading pH in water, lo ion pH paper must be used.

The paper I've got is actually Neenah (in the Yellow wrapping): this is the company which bought Wausau. So, it's the same paper. Yes, it's acid free. I am not sure what do you mean under "lignen": perhaps made with wood particles? I cannot say. Every paper is ligneous, in a sense.

I never tried it with saliva, so I don't know. I use it exclusively for cat urine, where ideal pH is 5.8 - 6.5 and "warning sign" is above 7, so the range of this paper is perfect for that. Now, I have read that an ideal person's saliva pH is JUST over 7 (maybe 7.1-7.4), so this paper SHOULD work fine since it's measurement range goes up to 8.

I'm not sure if it is acid free, but I use it to stretch my watercolor paper and it works great.

Soil pH. pH is a measure of acidity or alkalinity. pH 7.0 is neutral, pH 4.5 is acidic, like vinger. pH 9.2 is alkaline or basic, like calcium carbonate in antiacids, e.g., Tums, or lime. Lawns and other plants grow best at certain pH's.

Sorry. I bought this as a gift for my sister-in-law in another part of the country. I don't know the pH of her soil, but the plant is thriving.

The paper is bright white like snow. On the scale of 1-100 I would say it is a 96. I compared it to my bright, white HP paper to reach that conclusion.

I have no idea what the PH level is and I am not having any luck with this soil. I have not had such a problem where the seedlings die. Bagged soil seems to be very different lately. I am not sure if I can know what is in the mix. I am not happy that it does not seem like anyone can be trusted. I am just disappointed. Sorry that I can not answer your question.

The packaging says, "Archival." I wasn't sure if that meant acid-free or not, so I googled it. :) Google defines "archival" as - "A non-technical term which suggests that a substance is permanent, durable, and chemically stable. There is no guarantee that is the case. It is safer to look for acid free and lignin free when purchasing scrapbooking components." I don't know if you are looking to use the labels for scrapbooking or not. I use mine on the back of storage containers to hold information about the contents of the containers. Hope this information is helpful!

All parchment paper will degrade at 425, other papers that are organometallic will take higher temperatures. Get the silicon reusable pads. I love them!

Not sure. It's just a clear Elmer's glue. I used it for making slime for my kiddos and not on paper.
