The name of this compound, which I am writing here, just look at it carefully, fresh down, enjoying the diagram of the compound here to teach double bond and in this side Heritage B. R. In this side footage BR and he heritage beer. So the name of this compound age 44, 44 die brahman for for Debra Moon cyclone vaccine psychlo have seen. So according to the option in this problem. Obstinately, it's correct answer, obsession. D. H. Correct answer.
This question asked us to take a look at comparing some salts and the Civic Cat ions that can come from the salts in general. Wasn't really clear entirely what this question was asking for, but I believe we're being um as to determine which is the more acidic solution based on the salts and their concentrations here. So that means the lower ph solution that's going to be more acidic and it's gonna have a higher K. A value associated with it. And so we take a look at this. Um In the first set of examples we have nickel two plus chloride um at the same concentration of sodium chloride, sodium chloride with the sodium cat iron we should know is a neutral cat eye on. So it's not going to contribute any acidic properties at all to the solution. But Nicol two plus can I on has a K. A. Value associated with It's pretty small but nonetheless um will furnish some acidic properties to the solution. And so as a result here, The more acidic solution is going to come from the Nickel two plus here. And that would have um the lower ph overall for the solution as well. In the second set of examples, we have a tin two plus solution be compared to the same concentration of a cobalt two plus solutions. Were comparing tin and cobalt here. So the K value for 10 2 plus is four times channel the negative four for cobalt two plus, it's much lower, It's two times 10 on the negative 10. It's the higher K. A value that's going to give me a more acidic solution or a lower ph. So therefore the Tin two plus with the higher K value will furnish the more acidic solution. In this set of examples.
The answer's in the full moon.
Eso we want to know about, um a sulfuric acid solution 0.1 muller sulfuric acid solution on And we want to know the hydro Nia, my on concentration and ah, sulfuric acid, of course, is a strong acid. The first proton will disassociate 100% and give us 0.1 model airport once era Moeller I droning on my on, But then the hydrogen sulfate ion has got a pretty large K a for a weak acid points. It's 1 to 1.1 times 10 to the minus two, which is 20.11 So we are going to get a little bit mawr age plus from the 2nd 1 And so it's gonna be a little more than, uh, 10.1 Moeller because we get that from the first proton, plus a little from the second. But we're not going to get both of the protons to dissociate completely. So those are all out. And in fact, what we have seen is that the second Proton, once we've had 100% association or whatever dissociation of the 1st 1 then the 2nd 1 tends to give hydro Nia my on equal to the K a value. So the second Proton will give us this much high droning my on the 1st 100% So this much so when you add them to get 0.111 and so that would be the hydro me in my own concentration.
