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.
