1.Phosphoric acis (H3PO4) is a triprotic acid. How many mL of 0.04800M NaOH is required to neutralize 0.02500L of 0.1600 M phosphoric acid? (Hint: 3 moles of NaOH would react with 1 mole of phosphoric acid.)
2. You have standardized the NaOH solution that has a concentration of 0.05418 M. You are given a bottle of vineaga(acetic acid) with an unknown concentration. You carefully measured 0.02500L of the vineagar and 39.84 mL of standardized NaOH solution was used in the titration. what is the concentration of the vinegar? (Hint : 1 mole of vinegar reacts with 1 mole of NaOH)
hydroxylamine nitrate contains 29.17 mass % N, 4.20 mass % H, and 66.63 mass O. If its molar mass is between 94 and 98 g/mol, what is its molecular formula?
How much of the solution is needed?
When 2.8>g of NaOH were dissolved in 53.8>g of water in a calorimeter at 24.4oC, the temperature of the solution went up to 38.6oC. Find the value of delta H for one mole of NaOH.
would that be the same kind of functional group linking monosaccharides in long chain polysaccharides
