All you do now is compare this value with the value for protons. Also note that since we've done a molar conversion (the two calculations), we can just go ahead and consider those two values as concentration, i.e. .0002M instead of ...

It might be somewhere like a 5. So now we have a strong buffer with a lot of capacity, but our pH of this buffer solution is very different from the pH of just the weak acid/conjugate base we started with. Comment ( 4 votes) Upvote
Webb5 apr. 2024 · A 10 mM pH 8.0–8.1 phosphate buffer was prepared by dissolution of monopotassium phosphate (KH 2 PO 4, 0.68 g) and 1.0 M NaOH (4.63 mL, i.e., 0.19 g of NaOH) in Milli-Q water (500 mL). All solutions in buffer were prepared using this specific phosphate buffer unless stated otherwise. WebbIn theory, the pH of 0.1 M NaOH should be pH 13.0 (strongly basic). The pH of the ammonia solution should have been between 10 and 11. You should have noticed a difference in color with the test paper between the ammonia and NaOH solutions.
Webb25 apr. 2024 · Finally, we shall determine the molarity of the NaOH solution. NaOH(aq) —> Na⁺(aq) + OH¯(aq) From the balanced equation above, 1 mole of NaOH contains 1 mole of OH¯.
