You would add a Base.
dissolve 147 g in enough water to make 1 L of solution
To create a 400 L solution that is 62% acid, you would need 200 L of the 80% acid solution and 200 L of the 30% acid solution. This would result in a final solution with the desired concentration.
To make a 5% diluted acetic acid solution, you would mix 1 part of the 99% acetic acid solution with 19 parts of water (since 1 part acetic acid solution + 19 parts water = 20 parts total solution, and 1/20 = 5%). This will result in a 5% acetic acid solution.
To prepare a 1N solution of sulfuric acid (H2SO4), you would need to dissolve 49 grams of H2SO4 in enough water to make 1 liter of solution. Since the density of sulfuric acid is around 1.84 g/ml, you would need approximately 26.6 ml of H2SO4 to make a 1N solution.
A 50 ml solution that is 10% acid will consist of 5 ml of acid (10% of the volume) and 45 ml of water (90% of the volume). You're not adding any water, but you want to add enough acid to make a solution that is 50% acid and 50% water. You will need to have a total of 45 ml of acid in the mixture to make it a 50/50 solution, since the amount of water is also 45 ml. You have 5 ml in there already, so you would need to add 40 ml of acid. That would make a total 90 ml solution that is 50% water (45 ml) and 50% acid (45 ml).
Add 60g of Glacial Acetic Acid to a 1 liter volumetric flask. Make up to the mark with deionized water. The result is 1M acetic acid solution.
To make a solution of hydrochloric acid more dilute, you can add more water to the solution. This will decrease the concentration of hydrochloric acid in the solution while maintaining the total volume. Gradually adding water and mixing well will help in achieving the desired dilution.
To make a neutral solution acidic, you can add an acid like hydrochloric acid or sulfuric acid. This will increase the concentration of hydrogen ions (H+) in the solution, lowering the pH and making it acidic.
You need 256 litres.
To make a 9N (normal) Phosphoric Acid solution, you will need to know the concentration of your Phosphoric Acid. The formula to calculate the volume of Phosphoric Acid required is: Volume (in liters) = (Desired Normality * Equivalent Weight of Phosphoric Acid * Volume of Solution) / Concentration of Phosphoric Acid.
No, vinegar is a solution of acetic acid. Muriatic acid is a solution of hydrochloric acid - much stronger acicdity. Don't make salad dressing with Muriatic Acid!
For an eyewash solution, the measure would be one tablespoon of boric acid per one quart of sterilised water. (do not mistake deionized or distilled water. it must be sterile.)
