Ph Level Water Diagram
Each number represents a 10 fold change in the acidity basicness of the water.
Ph level water diagram. The common ph level of tap water generally coming from groundwater systems is 6 8 5. Tap water ph level varies but is usually 7 5. 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. The ph scale 0 14 is the full set of ph numbers which indicate the concentration of h and oh ions in water.
Distilled reverse osmosis water ranges from 5 to 7. Common bottled waters can have a ph of 6 5 to 7 5. But in the long run it would become. Bottled waters labeled as alkaline.
Bottled waters labeled as alkaline typically have a ph level from 8 to 9. Ocean water ph level is 8 and acid rain can measure in at 5 to 5 5. Distilled reverse osmosis water. Phs less than 7 are acidic while phs greater than 7 are alkaline basic.
As this diagram shows ph ranges from 0 to 14 with 7 being neutral. Environmental protection agency or epa consider tap water drinkable however it can cause different problems. For instance chlorine is not good for human consumption but the human body can technically tolerate it. The diagram on the left gives some relationships which summarizes much of the previous discussion.
