As a general rule, IRAs have an annual contribution limit of $5,000 per individual. There are income limitations which limit which IRA you can contribute to, for example, deductible IRAs, Roth IRAs and non-deductible IRAs.
The pH range is from 0 to 14, with 7.0 being neutral. Anything above 7.0 is alkaline, anything below 7.0 is considered acidic. Human blood stays in a very narrow pH range right around (7.35 - 7.45). Below or above this range means symptoms and disease.
The pH (or the amount of hydrogen ions (H+) in a solution) level of the blood is important in ensuring the proper functionality of biological systems. The optimal pH level of the blood is 7.4, which is maintained by three different types of buffer systems working in the body. The addition of an acid or a base to a substance changes its pH level. A buffer is a solution (or a substance) that has the ability to maintain pH and bring it back to its optimal value.
