What you add firstly in carbohydrate solution either H2SO4 or 1-naphthol?
what is the intermediate after adding H2SO4 on naphthol?
Why you add H2SO4 in the preparation of CUSO4 solution?
It's kind of hard to make copper sulphate without any sulphate being present.
If you add a bromophenol blue solution to .01M HCl what solution color would result after mixing?
yellowish
How do you prepare 2N H2SO4 and 2M H2SO4?
MW of H2SO4 is 98.08. 2M = 2 x 98.08 in 1 L of water (1 gram=1 ml). Take 500 ml water in a 1 L measuring cylinder. Add 196.16 ml slowly along the side into water in the measuring cylinder. Use 50 ml pipette with automated pipettor. If needed you may want to keep the cylinder in ice to take care of the heat generated. Then make up to volume to 1 L with water. Eq. wt for H2SO4 = 98.08/2 = 49.039. SO for 2N solution, 2 eq.wt in 1 L. 98.08 ml in 1 L water adopting the method cited above.
How do you prepare an aqueous 3.0 M solution H2SO4 from crystal H2SO4?
Start with 1 dm^3 (1 Liter) of pure H2O. Molarity is defined as Mol/dm^3, so this is generally an easy way to go. Measure out 3 mol of H2SO4 -> First find the molar weight of Sulfuric acid, which is, according to Google: 98.079g/mol. So 3 mol * 98.079g/mol = 294.24 grams of H2SO4. Add that to 1 Liter of water, and you'll have an aqueous 3 Molar solution!

Why we add conc sulphuric acid in mohr salt in the titration of mohr salt against potassium dichromate?
For preparation of standard solution of Mohr salt {FeSO4.(NH4)2SO4.6H2O}, it's necessary to add dilute H2SO4 to prevent the Fe2+ ions of Mohr salt solution from undergoing oxidation (to Fe3+).
What are two ways to make a solution more acidic?
Since acidity is a concentration of H+ ions, we can simply add them (in the form of an acid, such as HCl or H2SO4) or we can remove OH-. The easiest way to remove OH is to just add H, however.
How do you get back the color of turmeric after the reaction of turmeric and calcium hydroxide solution?
add lemon juice
What is the color produced when you add the phenolphthalien to sodium hydroxide solution?
You will get a pink to a pinkish-red solution depending on how concentrated the sodium hydroxide (NaOH) is.
What is foulger's reagent?
40g urea+ 80ml of 40%H2SO4! add 2g stannous chloride, heat untill solution is clear and make the volume upto 100ml. it is called foulger's reagent!
When you add color die to water is it called is it a solution or a solevent?
the die is called a solute the water is the solevent and when you mix the two together it is called a solution.
How do you prepare the 1.25 percent H2SO4 solution?
Concentrated H2SO4 is 96 %.( In laboratory ) As density of concentrated H2SO4 is 1.84gm/ml we will need this number as well, and as the atomic mass of H2SO4 is 98.08,as it is dibasic for normality it is 49 hence, Calculation=((96/100)(1000)(1.84))/49=36.04 If H2SO4 concentrated is 36.04 M then for make a 1L solution of 1M H2SO4 (36.04)X (x) = 1X(1) x = 1 X(1) / (36.04) x=0.0277gm/ml of water x = 27.7 mL of 36M H2SO4 per liter Hence for 1N H2SO4 dissolve 27.7ml of it to 1000ml of solvent(Water) that means for 0.1 N H2SO4 2.77 ml of it to 1000mL of solvent.
