what is the name of the reaction that causes displacement of the
salt? Displacement reaction? Re-precipitation reaction?
for e.g. , SO42- + BaCl2 -> BaSO4 + 2Cl-
Ionic precipitation.
No comments regarding your other posts. To one, irrelevant to A
level syllabus, don't waste your time. If you're itching to do some
calculation involving water, calculating the pKa of H2O (at 25
degrees Celsius) is more relevant to the syllabus. Try calculating
it out yourself before you google the answer. (Hint : you'll first
need to calculate the molarity of pure water, before you can
calculate the pKa of water).
To the other, you need to hands-on practice drawing and test
yourself on as many different (and unusual) structures as possible,
to test out for yourself your school guidelines to see if they're
useful for yourself or not.
As practice (all you JC students, school teachers and private
tutors reading this), try drawing out the full displayed structural
formula for the following species, showing all lone pairs, bond
pairs, formal charges, oxidation states, and dative bonds (if any),
for the following structures. Challenge yourself to draw them out
yourself first, before you google out the answer to check.
