Are there several trick questions there? It looks like it for some reasonWhat is the conjugate base of all these:
• Hydrochloric acid
• Sulfuric acid
• Hydronium ion
• Hydrogensulfate ion
• Acetic acid
• Carbonic acid
• Ammonium ion
• Hydrogencarbonate ion
• Water
• Hydroxide ion
I Will rep those who answer it the quickest correctly =]
Nope.Are there several trick questions there? It looks like it for some reason
• pH = - log10[H+]how do i find pH and [H+] of diprotic or triprotic acids?
can someone please go over finding pH and [H+] for me please?
thnks
Man I don't trust what I've learnthow do i find pH and [H+] of diprotic or triprotic acids?
can someone please go over finding pH and [H+] for me please?
thnks
lets say [H+] of phosphoric acid is 2M• pH = - log10[H+]
• [H+] = 10^-pH
Diprotic - 2 x [H+]
Tripotic - 3 x [H+]
-log[2x3] is correctlets say [H+] of phosphoric acid is 2M
so pH will be -log[2x3] yup?
but if it ionises 10% (making this up btw), then pH= -log(2x3x10%)
am i right?
please tell me im right.
this is a pretty noob question, but in equilibrium if pressure is changed and there are equal moles on prod and reactancts what way does it shift or is their no shift
Irrespective of if their is gases or not their will be no change if the amounts add up on both sides, however pressure is only relevant in gas equations anywaysdepends if they're all gases or not
I guess soo.. well I think so because only 1% of 0.1M ionises in solution, and since pH is a measure of [H+] ions, it seems logical.umm no.. i now get the diprotic, triprotic etc. bit
but idk about the degree of dissociation. lets say
acetic acid, ionises 1% in solution, and [H+]= 0.1M
so pH= -log(0.1x1%)
would that be right?
Ignore first part. I misinterpreted the questionwow you just confused me even more :L
so im right yes? :s
also Al2O3 is an example of an amphoteric substance? how do i prove it through an equation?

i can remember the equations, but how does it prove its amphoteric? looking by that do you look at Al's oxidation state?Al2O3 + 6 H+ --> 2 Al3+ + 3 H2O
Al2O3 + 3 H2O + 2 OH- --> 2 [Al(OH)4-]
