Precipitation Definition and 59 Threads

Hi. Im studying for a chemistry exam, and I am a bit unsure about something. As part of the electrochemistry component of the course i am required to know and understand various metal extraction processes. My book is fairly good for learning them, but one thing i am not sure about concerns the...

Hey Chem geniuses! I am a struggling high school chem student who couldn't combine water with water without blowing something up so some help would definitley be appreciated. My chem final has been issued already and it is as follows: Put 5 mL of 3 M aluminum chloride solution in each...

If two chemicals are mixed together If I had varying concentrations of the reactant solutions, why is it that the higher concentration mixtures will precipitate at a higher temperature? and lower concentration chemicals will precipitate at a lower temperature?

If two chemicals are mixed together, say: Na_2SO_4 + CaCl_2 --> 2NaCl + CaSO_4 If I had varying concentrations of the reactant solutions, why is it that the higher concentration mixtures will precipitate at a higher temperature? and lower concentration chemicals will precipitate at a lower...

Hi. If i was to conduct a few precipitation reactions, is there any reason why an unexpected precipitate will form, or any reason an expected precipitate will not be formed? I've though about things such as added ions in tap water (chlorine etc). Any other things?

Could the process of star formation in a collapsing gas cloud transform the process of virialisation and ultimately promote the formation of a central black hole? Consider the following idealised and oversimplified scenario. Suppose a gas cloud massive enough to generate vast numbers of...

I am cursed with a horrible textbook. In regards to a normal distribution: when given a mean and standard deviation, I can compute a probability of precipitation in inches with no problem. IE: when asked what is the probability that rainfall in a given area will exceed a given # of...

The mixing of which pair of reactants will form in a precipitation reaction? 1) HCl + Ca(OH)2 2) K2SO4 + Ba(NO3)2 3) NaNO3 + NH4 4) CsI + NaOH It is 2 because BaSO4 is insoluble?

I'm trying to understand the mechanisms behind precipate hardening, and I am not able to find a good source to explain the differences in coherent precipitates and dispersion hardening. I understand that the crystal structure of the precipitate is different in dispersion hardening (that's what I...
