anybody have any idea?

Question

I have a ques I just don't understand...anyone got any ideas?

Suppose you have a solution that might contain any or all of the following cations: Cu2+, Ag+, Ba2+, and Mn2+. Addition of HCl causes a precipitate to form. After the precipitate is filtered off, H2SO4 is added to the supernate and another precipitate forms. This precipitate is filtered off, and a solution of NaOH is added to the supernatant liquid until it is strongly alkaline. No precipitate is formed. Which ions are present in each of the precipitates? Which cations are not present in the original solution?

Answer 1

1st AgCL

2nd BaSO4

if there had been any Cu2+ then the OH- would have formed a precipitate with it (Cu(OH)2)

The Mn2+ may also have formed a precipitate if it was there the same way as Cu2+ so I don't think it is there but I'm not entirely sure of Mn(OH)2's solubility

Answer 2

I think you should stay home cook him his favorite meal then let hi relax. If you can decorate the house a little with roses if he appreciates that kind of thing. Run him bath water and let him soak. All that training probably wore his body down. Make sure while doing all this you remind him of how special he is to you and how much you love and miss him, tell him how much he means to you. This will pump his head up and make him feel like royalty. Wash him up gently then give him a relaxing massage. If you guys are having sex: Save the Good part for last. After all that time a way he might just want to hold you and savor the moment. If not give him whatever he wants that night and believe me even if you guys don't have sex he will feel like he is the only person that matters that night and it will be special. Trust me on this one. Afterward let him know again how wonderful he is and allow him to drift off to sleep. Full belly, feeling of being special, little work out, and pleasure ti end it. Have Fun! ;)
