A solution has a pH of 2.5. what is the H+
romanna [79]

<u>Answer: </u>The concentration of H^+ in the solution is 3.16\times 10^{-3}M

<u>Explanation:</u>

pH is defined as the negative logarithm of hydrogen ion concentration present in the solution.

pH=-\log [H^+]      .....(1)

We are given:

pH of solution = 2.5

Putting values in equation 1, we get:

2.5=-\log [H^+]

[H^+]=10^{-2.5}

[H^+]=3.16\times 10^{-3}M

Hence, the concentration of H^+ in the solution is 3.16\times 10^{-3}M

Name some ways that friction can be helpful and some ways it is harmful?
jeka57 [31]
Friction is helpful:
- We use it to brake for cars
- We use it to fly planes
-We wouldn't be able to turn a door knob without friction ( Our hand would just slide off it)

Friction harmful:
-Our cars would get much better gas mileage without tire and air friction
- There would be no skinned knees if friction didn't exist (Like when your skating or football)
- We could do some pretty cool dance moves without friction
- Our shoes would last longer without friction
