Calculate the pH of a $1.33 \times 10^{-9} M$ solution of LiOH.
So we want to know the ph of this lithium hydroxide solution and let him I'd rock side is strong base in a strong electrolyte And so all of that ID rock side, uh, will be produced as hydroxide. And so see, uh, h plus concentration can be obtained from thedc a W Any time that you know t h plus concentration or the O. H minus concentration, the hydro knee, um, or the hydroxide you can calculate the other. In this case, we know the hydroxide, and so we want to know the H plus. We divide both sides by the hydroxide concentration, and that will give us the concentration of the age plus. And the K W is one times 10 to the minus 14 and the hydroxide 0.82 polar. And so dividing. It's 1.22 times 10 to the minus 13 is the H plus concentration, and then the pH we can obtain from the H plus concentration. Remember, H blesses Justin abbreviation for the hydro knee in my on H 30 plus, and I already have that number on my calculator. So I'm just going to take the log of it and then change the side and I get 12 point 91
The Ph of 0.01 Normal Story. My condition is So we have any which anyone will break. Like this any place and which minus zero point double 01 normal consent percent. That is of any. Which Then over 2- concentration will be 0.0. Right? So concentration of H- will be 0001. So what will you The pos pos which is the minus low concentration of H minus, so minus log zero point double Genova. But even with cream, but we have to require value of ph ph plus P O. S equal to three. So P S will comes out here 14 14 minus three equals to 11. 11 is the correct
In this question, we have to stay which of the given Ph Fellows indicate an acidic solution at 25° indicates and which are basic and which are neutral. Now ibda ph value is more than seven, then the solution is basic. And if the ph hello is less than seven, then the solution is a city. and if the pitch is equal to seven, then the solution is neutral here, given the first one, Ph is 12.9 since it is more than seven. So the solution is basic. S ph greater than seven. For the second one, Ph 8.9 Here. Also, the solution is basic as Ph Greater Than seven. Then for the third one where ph value is 5.1, the solution is S E. D. Why? As the ph is less than seven And here 1.6 This solution also a CD solution is acidic as the ph Yes, less than seven.
Hello, everyone. My name is Ronny in this question in case first over one muehler ammonia, he would increase the concentration of the money so the concentration off H negative will be equal the route off the baby off the ammonium times by the concentration on the base of money. So it will be equal the root off 1.8 times. Boyton bore negative five times by the concentration one. So the total concentration would be 4.24 times fighting Bauer Negative three muehler. So we can calculate the value off P O. H, which is equal negative law, the concentration off h negative. So it will be to going to 37 So now we can calculate the value off pH, which is a 40 negative to the value off B o N church. Even living boy in 63 in case off opening to Moeller in a or edge. As we told the concentration off Richie, negative in case of a strong raise, is equal the concentration off a strong base times bible number off it So it will be or going to mourner also. So now we can calculate the value off B o h will be, oh, Boeing seven and saw the value off be actual be 13.3. So also in case of week is we increase the concentration, but it stills of the edge off the lower concentration strong busies higher. So we found the strong days usually have a higher P age than week. Based whatever we change, the concentration. Thank you.
