Чему равна концентрация каждого иона в насыщенном растворе сульфида серебра?

Dear Andrew, 
Thanks for your letter. It was great to hear from you again. 
You know, it's good that you asked me about such type of transport as a bicycle because I am the big fan of cycling. To be honest, bicycle riding is very popular among teenagers in my city. However, it doesn't have any special tracks for a bike ride so the better place for them is parks. I would have a great pleasure to take a part in a cycle racing because it can give me lots of fun, adrenaline and, also, a big experience. 
Anyway, hope you and your family are fine and I also wish you good luck with your concert! Write soon. 
All the best, 
Vika
