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.
Blood is normally slightly basic, with a normal pH range of 7.35 to 7.45. Usually the body maintains the pH of blood close to 7.40. A doctor evaluates a person's acid-base balance by measuring the pH and levels of carbon dioxide (an acid) and bicarbonate (a base) in the blood. Blood alkalinity increases when the level of acid in the body decreases or when the level of base increases.
