Ph Level Water Diagram
The ph scale 0 14 is the full set of ph numbers which indicate the concentration of h and oh ions in water.
Ph level water diagram. The diagram on the left gives some relationships which summarizes much of the previous discussion. Distilled reverse osmosis water. The common ph level of tap water generally coming from groundwater systems is 6 8 5. Distilled reverse osmosis water ranges from 5 to 7.
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. But in the long run it would become. 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.
Phs less than 7 are acidic while phs greater than 7 are alkaline basic. Bottled waters labeled as alkaline. Each number represents a 10 fold change in the acidity basicness of the water. Ocean water ph level is 8 and acid rain can measure in at 5 to 5 5.
Common bottled waters can have a ph of 6 5 to 7 5. H ion concentration and ph relate inversely. As this diagram shows ph ranges from 0 to 14 with 7 being neutral. Bottled waters labeled as alkaline typically have a ph level from 8 to 9.
