why aluminium chloride solution is pale yellow.
Aniket:
Dear Feiends,
Al2(So4)3 + 3Na2Co3+3H2O -------> 2Al(OH)3+3co2+3Na2So4
342.15 +317.94 +54 --------> 156+132.03+426.12
As per this Equation formation of aluminium hydroxide is 156 gm theoritically but practically got higher yield why?
is there any other formation during reaction ?
AWK:
From inaccurate work, you should not immediately draw subversive conclusions for chemistry.
For aluminum hydroxide, thorough washing of the precipitate and subsequent long drying is very important.
Capital letters for elements are also very important
chenbeier:
How do you check your Product. Weight? Dry enough, maybe also sodiumtetrahydroxyaluminate Na[Al(OH)4]?
AWK:
Sodium tetrahydroxyaluminate Na[Al(OH)4] is rather not important for this reaction with sodium carbonate. Moreover, this compound is soluble in water.
Aniket:
Dear Sir,
Drying method is spray drying.
Product pass in British Pharmacopoeial Requirements.No chance of any impurity or other salt.
