Hello, everyone. My name is Ali. Now we will answer the questions that we have mixed for here. It's consisting off H E and 02 glass key in tow. This make sure is acidic buffer existing in volume on going toe. Five litre because he said 500 elite or so it's open five liters. The concentration off each in orderto is open. One more clarity and the concentration off key and auto is a 0.15 polarity. And he told it, You know, too is weak acid as a B K is equal. Three boys 34 The question here is which Well, it happened when we and one off this compound tow these power formation is we exceed their buffer range or no, but the meaning off exceeded the proper range or not the buffer rangy. If we can squeeze a B age off these perform, it will be equal beak, a blast look, the concentration off K and on toe divided by each in or two and by substitue will be sweep on 34 plus. Look the concentration off K in order which is open on five and consideration off each end or two which is open it one and the result be h will be 3.516 this be H, which is 3.516 The buffer capacity is maximally to increase the bee etch by one. So from 3.516 to 4.516 or two 2.51 Sex wen will not be exceeded zuppa for rage but more than this by two unit. Or they listened this by one unit. That's mean me exceeds up off our past from the definition, a buffer capacity to increase the beach by one or decrease it by one. So now in the 1st 1 he said, we will add, So do you mind ropes Sign which it's amount. 200 and 50. Mellie Grant. Does this represent the helm in your morn? It represent 250 times pointing negative three grand, divided by its molecular weight, which is 40 grammar moon when she's representing him anymore, or point or 6 to 5. So what have been willingly exist? Amount is a buffer. Capacity will be exceeded or no Now nobody is Noh What effect on edge in or two it decrees its amount. So the new concentration off each and you will be the initial number off moon off H in order to which is all going to one time spy opening. Fine. Negative. Tow the number off more off in which added, which is all point or 6 to 5 divined it by then. You won't and its effect on the concentration off K and auto, which is a congregate based soccer basic, saw the intellectual increase its amount, so its initial amount is on 0.15 times by or going five litre, which is a present, the number of more plus the number of moon added, which is all point or 6 to 5 divided by the voice. So now when we calculated and you'll be agin you, it will be the beacon a which we steal it before it's just three points. 34 Blast Look, Zach, Concentration Off K and two, which she's a stated here, opine on five times by open front glossies. It's a value off. These ethical created by calculator is all point or fine. Six to fi and the value off these is O point for 37 fine, so by substituted here it will be over 0.56 Toe finder Volume in the year or point. All 4375 My violet on volume goes volume. So when we calculated we found a new B H is 345 by combining is a B H new after having disease amount off no edge with the initial value 3.516 So we found that the steel's about far no exceeded its a buffer capacity. That's me. We still in a bar for rage. So all these amount of you know EJ not exceeding the buffer capacity. But what about the other solution? We will substitute. You don't like these muscle for the other three solution and we will found that we steal in a buffer range not exceeded. Okay. Thank you.
