Please reply as soon as possible, I really need the answer urgently. How many grams of NaOH are required to completely neutralize 100ml of 1M solution of H2SO4?
Start with the equation for the reaction
NaOH + H2SO4 -> Na2SO4 + H2O
which you need to balance.
Then from the equation how many moles of NaOH react with each mole of H2SO4?
Calculate number of moles of H2SO4 used (M)
M=0.1 x 1 M =
How many moles of NaOH needed? (N)
Calculate molecular mass of NaOH (MM)
mass required = MM x N
Thanks for help,
Just a bit of confusion,
Upon balancing, he equation appears like this:
2NaOH + H2SO4 --> Na2SO4 + 2H2O
So it is clear that 2 moles of NaOH are needed to react each mole of H2SO4, then why use M = 0.1 x 1M = ?
And what's 0.1 in this formula?
Awaiting your reply.
To determine how many grams of NaOH are required to completely neutralize 100ml of 1M H2SO4 solution, you need to follow these steps:
Step 1: Find the number of moles of H2SO4.
Molarity is defined as moles of solute per liter of solution. The given solution is 1M H2SO4, which means there is 1 mole of H2SO4 in 1 liter of the solution. In this case, you have 100ml of the solution, which is 0.1 liters. So, to find the number of moles of H2SO4, you multiply the molarity by the volume (in liters) of the solution:
Number of moles of H2SO4 = Molarity × Volume
= 1M × 0.1 L
= 0.1 moles of H2SO4
Step 2: Determine the stoichiometry of the balanced chemical equation.
The chemical equation for the reaction between NaOH and H2SO4 can be written as follows:
2 NaOH + H2SO4 -> Na2SO4 + 2 H2O
From the balanced equation, you can see that 2 moles of NaOH are required to completely neutralize 1 mole of H2SO4.
Step 3: Calculate the number of moles of NaOH required.
Using the stoichiometry of the balanced equation, you can determine the number of moles of NaOH needed to neutralize the given moles of H2SO4. Since the ratio of NaOH to H2SO4 is 2:1, you multiply the number of moles of H2SO4 by 2:
Number of moles of NaOH = 2 × Number of moles of H2SO4
= 2 × 0.1 moles
= 0.2 moles of NaOH
Step 4: Convert moles to grams.
To convert moles of NaOH to grams, you need to know the molar mass of NaOH. The molar mass of NaOH is approximately 40g/mol. Multiply the number of moles of NaOH by the molar mass:
Mass of NaOH = Number of moles of NaOH × Molar mass of NaOH
= 0.2 moles × 40 g/mol
= 8 grams
Therefore, to completely neutralize 100ml of 1M H2SO4 solution, you would need approximately 8 grams of NaOH.
