What is the absorption peak(s) of bromocresol green? Make sure to write down the wavelength at which the absorption peak(s) occur. Include units, please 2.Are the absorption spectrums and peak(s) for methyl orange and bromocresol green the same? Why or why not?

3. Show the calculation of (1) the expected grams of alum (KAI(SO4)2 12 H2O) formed from the reaction of 1.4 grams of aluminum metal and then show the calculation of (2) the % yield if the actual yield of alum is 21.31 grams. Overall reaction is shown below: 2 Al + 2 KOH + 10 H2O + 4 H2SO4 →2 KAI(SO4)2 12 H2O + 3 H2(g)T
