What will be the pH of a buffer solution prepared from $0.20 \mathrm{mol} \mathrm{NH}_{3}, 0.40 \mathrm{mol} \mathrm{NH}_{4} \mathrm{NO}_{3},$ and just enough water to give 1.00 $\mathrm{L}$ of solution?

Let's calculate the pH of this buffer solution in one leader of solution, the military ity of NH three. We can calculate. We're told we have 0.20 moles in one leader, and this will give us 10.20 Mueller. We can calculate also the polarity Love the N H four n 03 which is equal to 0.40 malls over one leader in this works at 2.40 Moeller NH 403 is a salt which would associate to NH four plus and and all three minus. If this is 40 Mueller, the NH four plus majority is 40 Mueller therefore using this. Let's calculate, Let's start with a buffer and it's three mm at H 20 NH four plus and which minus initial mill Arat E and H 3 to 0 and H 440 zero. Change in equilibrium minus X plus X plus x in 20 minus x Put 40 plus X and x k B expression here his NH four plus, which minus over an H three Looking at the baby, we know what's 18 times 10 to the negative. Five will substitute our values in here. 40 plus x x and 0.20 minus X solving for X published into my equations over here we're going to get for many times under the 95. His reminds X on Wait 40 plus X solving. We'll take the positive roots on Lee and I get 90 times 10 to the negative six. Therefore, going back to my ice table, the O. H. Minus Similarity works out to 9.0 times 10 to the negative six Mohler we can solve for the P O. H, which is equal to negative log 9.0 times 10 to the negative six that would be equal to 5.5 and pH value it's 14 minus 5.5 works out to a pH of 8.95
