naoh h2so4 c2h5oh naoh Preparation of NaOH solution: Add 16-17 mL of 6M NaOH to a 500 mL bottle and fill it to the shoulder with distilled water. The 6M NaOH is not made up with quantitative accuracy, so your diluted solution will be approximately, but not exactly, 0.2 M. Close the bottle with a rubber stopper and mix very thoroughly by repeatedly inverting and
so2 + naoh Let's assume we have 100 g of the 40% w/w NaOH solution. This means we have 40 g of NaOH and 60 g of water. Step 3: Calculate Moles of NaOH. The molar mass of NaOH is approximately 40 g/mol 23 + 16 + 1. Therefore, the number of moles of NaOH is: Moles of NaOH = 40 g / 40 g/mol = 1 mol. Step 4: Calculate Molality
naoh + h2so4 Để xác định công thức của oleum H2SO4.nSO3 thu được trong quá trình sản xuất sulfuric acid, người ta pha loãng 8,36 gam oleum vào nước thành 1,0 lít dung dịch sulfuric acid, sau đó tiến hành chuẩn độ mỗi 10,0 mL dung dịch acid này bằng dung dịch NaOH 0,20 M. Thể tích NaOH trung bình cần sử dụng để chuẩn độ là 10,0 mL
