Ph Level Water Diagram

Each number represents a 10 fold change in the acidity basicness of the water.

Ph level water diagram. Estimates of future carbon dioxide levels based on business as usual emission scenarios indicate that by the end of this century the surface waters of the ocean could have a ph around 7 8 the last time the ocean ph was this low was during the middle miocene 14 17 million years ago the earth was several degrees warmer and a major extinction event was occurring. Phs less than 7 are acidic while phs greater than 7 are alkaline basic. Bottled waters labeled as alkaline typically have a ph level from 8 to 9. Water with a ph of five is ten times more acidic than water having a ph of six.

Environmental protection agency or epa consider tap water drinkable however it can cause different problems. H ion concentration and ph relate inversely. The diagram on the left gives some relationships which summarizes much of the previous discussion. Bottled waters labeled as alkaline.

As this diagram shows ph ranges from 0 to 14 with 7 being neutral. The common ph level of tap water generally coming from groundwater systems is 6 8 5. Common bottled waters can have a ph of 6 5 to 7 5. For instance chlorine is not good for human consumption but the human body can technically tolerate it.

Tap water ph level varies but is usually 7 5. But in the long run it would become. Every type of water has its own ph. The ph scale 0 14 is the full set of ph numbers which indicate the concentration of h and oh ions in water.
