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.
Alkaline water is water with a pH higher then 7.0. The pH of water is the difference between how much hydrogen (h+) water has vs. how much hydroxyl (oh-) water has. Water is H+OH- or H2O. If you add minerals with more H in them then OH the pH goes down. If you add minerals with OH- in them then pH goes up.
