The two simplest sequences to work with are arithmetic and geometric sequences. An arithmetic sequence goes from one term to the next by always adding (or subtracting) the same value. For instance, 2, 5, 8, 11, 14,... is arithmetic, because each step adds three; and 7, 3, â1, â5,... is arithmetic, because each step subtracts 4.
Report Abuse. Yes pH is temperature dependent. So if you have water with a pH of 6.9 (very mildly acidic) at 12 C, and raise the temp up to about 22 C, the pH will reduce to about 6.7, which is more acidic. Jason, only pure water is neutral... most water you come across on a daily basis is not pure and doesn't have a pH of 7. derekbradley4000 Â· 8 years ago.
Because of the high proportion of hydroxyl ions in alkaline ionized water, the water is alkaline meaning it has a high pH or pH above 7. On the pH scale, 1-6 is acidic, 7 is neutral, and 8 and above is alkaline. The body pH scale ranges from acid to alkaline, with 0 being the most acidic, and 14 being the most alkaline.
