Beside the usual method of titrating with KMNO4, what is/are the alternative method/s to test for the presence/amount of oxalate in a compound?
-8<3x-5<-4 -8<3x-5 and 3x-5<-4 3x-5>-8 3x<1 3x>-3 x<1/3 x>-1 therefore 1/3>x>-1
Is Al(OH)3 soluble in KOH or K2C2O43H2O?
Why is heating required for this formation: 6NaOH (aq) + Al2(SO4)3 (aq) ¨ 2Al(OH)3 (s) + 3Na2SO4 (aq)? Wouldn't freezing favour the formation of Al(OH)3 since freezing lower the KSP and more Al(OH)3 would precipitate?
This is the equation for the formation of Al(OH)3: 6NaOH (aq) + Al2(SO4)3 (aq) ¨ 2Al(OH)3 (s) + 3Na2SO4 (aq) Would any side products be formed if NaOH was added quickly into Al2(SO4)3?
During the preparation of K3[Al(C2O4)3].3H2O, NaOH was added slowly and with stirring over an approximately 10-minute period to a solution of Al2(SO4)3 solution. The combined solution was heated to almost boiling and left to stand for a few minutes. 1. Why does NaOH added slow...
I calculated the average number of crashes over a 240 week period to be .0875... what formula do I use to calculate the probability that at least 19 crashes would occur over that 240 week period?
A room has a volume of 120 m^3. An air-conditioning system is used to replace the air in the room every twenty minutes, using ducts that have a square cross ection. Assuming that air can be treated as an incompressible fluid, calculate the length of a side of the square if the...
