Question

Explain how the PH of a solution is determined

Answer 1

Answer 2

PH is defined as Negative Logrithm to the base 10 of molar Hydrogen ion concentration. PH depends on the concentration of Hydrogen ion. For example in HCL acid 0.0001molar is equal to -log (10 power -4). This gives a PH value of +4. Pure water is 0.0000001Molar gives +7. Thus acidic is 0 upto 7. 7 is nuetral. Basic is above 7. pH scale is defined in practice as traceable to a set of standard solutions whose pH is established by international agreement.Primary pH standard values are determined by the Harned cell, a hydrogen gas electrode, using the Bates-Guggenheim Convention

Answer 3

omg thats a lot lol. Thank you :)

Answer 4

Np

@Da_Homie

Answer 6

ideas??

Answer 7

umm.. tbh.. i have none :( :p Im no good at science.. and i tried looking it up, but i did find anything helpful

Answer 8

lol ok hold on

Answer 9

k

Answer 10

*did not find anything helpful

Answer 11

In chemistry, pH (/piː eɪtʃ/ or /piː heɪtʃ/) is a measure of the acidity or basicity of an aqueous solution. Solutions with a pH less than 7 are said to be acidic and solutions with a pH greater than 7 are basic or alkaline. Pure water has a pH very close to 7.- googled it :P lol

Answer 13

ohhh.. see this^ was NOT in my online textbook (i go to online school) :p dude you have been a lifesaver, thank you so much. I cant give you a medal, because i already gave one to @amberxoxo but if i could, i would

Answer 14

you can undo metals lol

Answer 15

medals*

Answer 16

there you go :)

Answer 17

lol thx

Answer 18

yw! :D

Answer 20

It depends. If you're doing an experiment then you can use a PH meter to determine the pH of the solution. If you're solving it theoretically, the way you solve it also depends on the given information.
The most common formula for solving pH is \(\sf pH=-log[H^+]\).
If pOH is given you can simply solve pH=14-pOH.
For more complicated situtations (like titrations and buffers).. henderson hasselbalch equation may help you: \(\sf pH=pK_a +log\ \frac{[A^-]}{[HA]}\), where \(\sf pK_a=-log K_a\) and \(\sf [A^-]\) is the concentration of the conjugate base and \(\sf [HA]\) is the initial concentration of the acid in the solution.
