Calculate Volume NaOH: Calculate the volume of sodium hydroxide used in the titration by subtracting the initial buret reading from the final buret reading.Volume NaOH =Final buret reading−Initial buret readingVolume NaOH =25.64mL−3.45mLVolume NaOH =22.19mL
Convert to Liters: Convert the volume of sodium hydroxide from mL to L because concentration is given in moles per liter (M).Volume NaOH (L)=1000Volume NaOH (mL)Volume NaOH (L)=100022.19mLVolume NaOH (L)=0.02219L
Find Moles of NaOH: Use the molarity of sodium hydroxide and its volume to find the moles of sodium hydroxide.Moles NaOH = Molarity NaOH ∗ Volume NaOH (L)Moles NaOH = \(0.984 \, M ∗0.02219 \, LMoles NaOH = 0.02184 \) moles
Write Chemical Equation: Write the balanced chemical equation for the reaction between sodium hydroxide and sulfuric acid.NaOH+H2SO4→Na2SO4+2H2O
