How is carbon 14 formed?
Carbon-14 is continually formed in nature by the interaction of neutrons with nitrogen-14 in the Earths atmosphere; the neutrons required for this reaction are produced by cosmic rays interacting with the atmosphere.
What is a pH of 10?
The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic .Most H+ ions: pH = 4; or pH = 5.Answer 4Most OH- ions: pH = 10; or pH = 13.Answer 13Least H+ ions: pH = 12; or pH = 13.Answer 137 more rows
What is a pH meter called?
The pH meter measures the difference in electrical potential between a pH electrode and a reference electrode, and so the pH meter is sometimes referred to as a potentiometric pH meter. The difference in electrical potential relates to the acidity or pH of the solution.
