What the molar hydrogen concentration and molar hydroxide concentration of the pH=6?
Answer:
pH = log1/[H+] =6
you have pH+pOH =14 (at 25°C)
pOH = 14-pH =14-6 =8
and with analogy to pH ;
pOH= log1/[OH-] = 8
log1/[OH-] = 8 hence log [OH-] =-8
AND [OH-] = 10^-8
ch=2squared
H+ = 10^-6
OH- = 10^-8
pH is determined by the exponent of the hydrogen ions. When the numbers are multiplied together, they should give you 10^-14. It's a property of water.
molar hydrogen conc. is 10^(-6)
molar hydroxide conc. is 10^(-8)
u can check backwards:
pH = -log (molar hydrogen conc.)
(log to base 10)
& use pH + pOH = 14
