Make a 3% dilution with a 20 litre barrel of 38% nitric acid:
1. Pour half of the required water into a barrel (e.g. one of 500 l) - in this case 147 litres of
water.
2. Use personal protective equipment to protect your skin and eyes.
Carefully pour the 20 litre barrel of 38% nitric acid into the barrel of water (without splashing
or spilling).
3. Also pour the rest of the water, 147 litres, into the barrel.
4. Stir gently with an acid-resistant stirrer so that the acid is mixed well.
With a 20 litre barrel of 38% nitric acid (24.8 kg), 312 litres of 3% nitric acid can be made by first
pouring 146 litres of fresh water into a barrel containing sufficient volume, then the 20 litres of nitric
acid and then the remaining 146 litres of water.
With a 20 litre barrel of 53% nitric acid (26.7 kg), 470 litres of 3% nitric acid can be made by first
pouring 225 litres of fresh water into a barrel containing sufficient volume, then the 20 litres of nitric
acid and then the remaining 225 litres of water.
With a 20 litre barrel of 68% nitric acid (28.2 kg), 640 litres of 3% nitric acid can be made by first
pouring 310 litres of fresh water into a barrel containing sufficient volume, then the 20 litres of nitric
acid and then the remaining 310 litres of water.
