Take 1 ml of 98% acid and add to 3 ml of water to get 25% acid. Total volume will be 4 ml (in this case). You can scale up this to any volume you need.
(always add acid to water and not water to acid)
Weight of 25% sulfuric acid per gallon
Sulfuric acid is more stronger than Nitric acid, but Nitric acid is more reactive than Sulfuric acid.
Add 0,8 L of water.
Use distilled water to dilute it to your desired concentration.
About 80ml of water must be added to 40ml of a 25 percent by weight solution to make a 2 percent by weight solution.
Weight of 25% sulfuric acid per gallon
the purity of the acid is 25%
Sulfuric acid is more stronger than Nitric acid, but Nitric acid is more reactive than Sulfuric acid.
6 litres of 50% + 4 litres of 25%
Add 0,8 L of water.
16 2/3 liters
10 liters.
Use distilled water to dilute it to your desired concentration.
Multiply by 100: 25 x 100 = 2,500%
25 percent of 25 percent = 0.0625
15% + 25% = 40%
About 80ml of water must be added to 40ml of a 25 percent by weight solution to make a 2 percent by weight solution.
