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.
How Water pH may affect your health. The pH of the water you drink matters. Alkaline water has a pH of higher than 7, which it gets from healthy essential minerals that you need for better health. Acidic water has a pH of less than 7, and often lacks the minerals you need for good health. Water pH and Alkalinity is NOT the same thing!
