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.
Soon they outnumber the hydrogen ions, and the water turns alkaline (blue in color). pH is a measure of how acidic a solution is. The pH scale ranges from 0 to 14. Solutions with a pH of less than 7 are acidic, and those with a pH greater than 7 are basic (or alkaline).Distilled water is neutral and has a pH of 7. Knowledge of pH is important because most aquatic organisms are adapted to live in solutions with a pH between 5.0 and 9.0.oon they outnumber the hydrogen ions, and the water turns alkaline (blue in color). pH is a measure of how acidic a solution is.
