Problem 108 Hard Difficulty

What is the pH of 1.000 L of a solution of 100.0 g of glutamic acid $\left(\mathrm{C}_{5} \mathrm{H}_{9} \mathrm{NO}_{4}, \text { a diprotic acid; } K_{1}=8.5 \times\right.$ $10^{-5}, K_{2}=3.39 \times 10^{-10} )$ to which has been added 20.0 g of NaOH during the preparation of monosodium glutamate, the flavoring agent? What is the pH when exactly 1 mol of NaOH per mole of acid has been added?

Video Transcript

the number off moles off sodium hydroxide and bloom Arctic acid in a solution can be calculated. A shoe de moler off the molar mass off sodium hydroxide is 39.9971 We can calculate the number off moles off sodium hydroxide on Muller. Mask off Luke. Dramatic Asset is 1 47.130 We can also calculate the number off moles dramatic asset when exactly one mole off anywhere, it is added. One more off asset, one more off gloom eight iron is form which for the reacts with water. Therefore, it can be concluded that 0.500 mole, which negatively acts with 0.500 cool off dramatic asset to produce bloom eight irons. The number of moles off dramatic acid left is point one needs a removal. Considering the falling reaction, we have expression for equilibrium. Constant. The initial and equally brim concentration for this system is shown in the tabular farm. Now, to find the value off ex substitute the equilibrium concentration into the given expression. Ex turn out to be 3.6 into Denree super minus five. This value off X is less than 5% off 0.180 in on a 0.500 This assumption is therefore valid. The equilibrium concentration off hydro new mine in this solution can be the domain from its initial concentration on dhe. Changing that concentration has indicated in the last line off table. Thus, the equally broom concentration off hide Rooney and I'm turns out to be 3.6 into 10 days ago, minus five. The pH we can deter mined from develop the concentration off hydro new mine. It is negative. Log off concentration off hydro in your mind which gives us the ph 4.5.
