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.
Many people donât know that water can be different pHâs. The pH scale ranges from 0 to 14. 0 is the most acidic water and 14 is the most alkaline water. You donât want to drink acidic water because it is oxidizing to whatever it comes in contact with, meaning it will damage it. But most of bottled water and tap water is, in fact, acidic, and Americans are guzzling it down every day.
