Depends on what you mean by more, but a pH12 more basic than pH10 because it has fewer H+ ions per liter.

The term "ph1" does not have a standard meaning in mathematics or science. It appears to be an incomplete or incorrect reference. If you can provide more context or clarify the question, I'd be happy to help with finding a solution.
"Ph1" doesn't have a recognized meaning or context in English language or commonly used terminology. If you provide more information or context, I may be able to help further.
If you mean a universal indicator, it is used to detect if a chemical is acid, alkali or neutral. It changes colour to show the chemicals position on the pH scale A universal indicator turns red at pH1 (Very acidic), orange at pH4 (Fairly acidic), yellow at pH6 (Not very acidic) and green at pH7 (Neutral). It turns more dark blue as it gets to pH10 (Quite Alkaline) and more to purple by ph12 (Even more alkaline) and to a dark purple by pH14( Very Alkaline).
it is the strongest acid e.g battery acid
"Ph1 acid" does not refer to a specific chemical compound or term in chemistry. It may be a typo or a misunderstanding. If you provide more context or correct the term, I can give you a more accurate answer.
pH1 likely refers to a solution's pH level being close to 1, indicating a very acidic solution. pH is a measure of the acidity or basicity of a solution on a scale of 0-14, with lower values indicating greater acidity.
