Gram of naoh
WebApr 30, 2014 · Explanation: You will need to know the molarity of the NaOH. Let's assume the solution is 0.1M. NaOH is a strong base, so this will produce 0.1mol/L of OH ions in solution. This will produce a pH of 13. You will need to take the negative log of 0.1 to find the pOH. This will work out to be 1. We can calculate the pH to be 13.

WebNumber of moles of NaOH = mass ÷ relative formula mass = 20 ÷ 40 = 0.5 mol. From the equation, 2 mol of NaOH reacts with 1 mol of Na 2 SO 4, so 0.5 mol of NaOH will react with 0.25 mol of Na 2 SO 4. WebFirst, convert the mass of NaOH to moles. Second, calculate the molarity of the NaOH solution. Because NaOH is a strong base and is soluble, the [OH −] will be equal to the concentration of the NaOH. Third, use Kw to calculate the [H +] in the solution. Lastly, calculate the pH. Step 2: Solve.
