Why does adding hydrochloric acid to an aqueous solution of a carboxylic acid decrease its solubility in water?
Q. A) The added acid makes the solution more ionic B) The added acid shifts the acid dissociation equilibrium in the direction of the non-polar protonated form of the acid. C) The added acid makes the carboxylic acid dissociation constant, Ka, smaller. D) The added acid makes the carboxylic acid dissociation constant, Ka, larger. E) The added acid influences the kinetics of solubility not the thermodynamics. Please provide explanation, as to why you chose an option, and why the others are incorrect.

What concentration of gibberellic acid should i use on ferns?
Q. i need to do a science experiment and i am using gibberlelic acid on C-ferns. i need to know the amount of ppm of gibberellic acid would kill the fern so i dont use that much. i need to make different concentrations of the solution but i want to make it enough to work but small enough not to kill the plant.

A. Not sure but I do know that table grape growers use GA to plump the fruit- elongates it.

How long should lactic acid last and how do i know if its lactic acid?
Q. I had a hard practice and the next day i barley could move my leg but i walked on it the whole day and i can move it now but it still hurts. I can barley straighten out my leg without the pain getting worse. Its kind of like a pain thats just push on my mucles and bones. Ive had it for 5 days now and it still has a pain. Is this lactic acid and if it is when will it go away?

A. If the pain is the same or getting worse, it may be not lactic acid. Usually the best way to get the lactic acid out of your muscles is more movement + mineral water (the real thing, not just carbonized water). Are you sure that the pain is in the muslces and not joints? Since you've been moving around, 5 days sounds like a really long time (to me). Unless you're not replacing your body fluids properly (try these electroylte drinks, mineral waters etc.) it might be some kind of another injury (tear or even rip of other tissues), see a health care provider: a) if there is no change in pain b) if it doesn't improve at all with the aforementioned addictions good luck!
