The chemical equation is as follows: 2NaCl(aq)+2H2O(l)→2NaOH(aq)+Cl2(g)+H2(g. … Step 4: Stability the hydrogen atoms.
How do you calculate sodium hydroxide?
Step 1: Calculate the quantity of sodium hydroxide in moles
- Quantity of solute in mol = focus in mol/dm 3 × quantity in dm 3
- Quantity of sodium hydroxide = 0.100 × 0.0250.
- = 0.00250 mol.
- The balanced equation is: NaOH(aq) + HCl(aq) → NaCl(aq) + H 2O(l)
- So the mole ratio NaOH:HCl is 1:1.
