... ok thx...

Answer 8

No one was helping and I didn't know how to do this so link can better help you than me

Answer 9

what is pH?

Answer 10

a numeric scale used to specify the acidity or basicity (alkalinity) of an aqueous solution

Answer 11

the pH is basically a measure of the acidity and alkalinity of a solution.
pH values below 7 means that the solution is acid and above 7 that its alkaline.
The lower the pH the more acid so lemon juice pH 2.3 is more acid than beer pH 4.1.

Answer 12

ok.... so like the richter scale, does it get more acidic exponentially?

Answer 13

pH is defines as - log {h] where h is the molar concentration of hydrogen ions in the aquesous solution.

Answer 14

In english plz XD

Answer 15

Its a logarithmic scale.

Answer 16

ok...

Answer 17

whats h.

Answer 18

h is the concentration in moles per liter of hydrogen ions H+

Answer 19

so like 2.3 and 4.1?

Answer 20

pH of 7 means the solution is neutral. The concentration of H+ = concentration of OH-

Answer 21

...........

Answer 22

2.3 is the pH which is - log of concentration of H+

ph 2.3 is equivalent to concentration 10^(-2.3) of H+ ions.

Answer 23

you mean order of mag diff between the two?

Answer 24

ok. yeah

Answer 25

Its more convenient to use simple numbers that numbers like 10^-2.3

Answer 26

The lemon juice's order of magnitude is 1.8 more acidic than beer

Answer 27

yeah

Answer 28

THX SOOO MUCH WELSHFELLA!!!
