Pure water has a pH of 7.0. What must be the concentration of hydrogen ions in pure water? 1 × 10^–14 M 1 × 10^–7 M 1 × 10^7 M 1 × 10^14 M

1x10 ^—7M

Explanation:

From the question, we obtained the following information:

pH = 7

[H+] =?

pH = —Log [H+]

7 = —Log [H+].

Take the anti-log (—7)

[H+] = 1x10 ^—7M

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
