How much pure acid must be added to 12 ounces of a 40 percent acid solution in order to produce 60 percent acid solution?
To find the amount of pure acid to add, set up an equation based on the amount of acid in the original solution and the final solution. Let x be the amount of pure acid to add. The amount of acid in the original solution is 0.4 × 12 = 4.8 ounces. The amount of acid in the final solution is 0.6 × (12 + x) = 4.8 + 0.6x ounces. Therefore, to get a 60% acid solution, you would need to add 10.67 ounces of pure acid.
How much pure acid is in 860 milliliters of a 19 solution?
To calculate the amount of pure acid in the solution, you can use the formula: amount of pure acid = volume of solution * concentration of acid. In this case, it would be 860 mL * 0.19 = 163.4 mL of pure acid in the solution.
Is a water solution of a strong acid always concentrated?
Not necessarily. The concentration of a strong acid in water depends on the amount of acid dissolved in the water. A solution is concentrated if there is a relatively large amount of solute (acid) dissolved in the solvent (water), and dilute if there is a relatively small amount.
How much acid is needed to reduce the pH from 12 to 8?
To reduce the pH from 12 to 8, you would need to introduce an acid that is strong enough to lower the alkalinity by 4 units on the pH scale. The exact amount of acid required would depend on the specific properties of the acid and the volume of the solution being adjusted. A titration experiment would be a practical way to determine the amount of acid needed.
A small amount of acid is added to a buffer solution the pH of the solution will?
A small amount of acid is added to a buffer solution. The pH of the solution will stay about the same.
The acid which reduces Fehling's solution is?
The acid that reduces Fehling's solution is ascorbic acid (vitamin C). It causes the blue solution to turn into a brick-red precipitate of cuprous oxide.
How can an acid be neutralised?
An acid can be neutralized by adding a base to it. The base will react with the acid to form water and a salt, which will reduce the acidity of the solution. The amount of base needed to completely neutralize the acid depends on the strength and concentration of the acid.
A solution containing large amount of solute in comparison to solvent is?
A solution that contains a large amount of solute when compared to the volume of the solvent is called a concentrated solution. Examples of concentrated solutions are hydrochloric acid and sulfuric acid. A dilute solution is one where the amount of solute is small compared to the solvent.
Does diluting an acid give a more concentrated solution?
no it doesn't.dissolving or making a solution of an acid makes a more dilute solution of the acid.
Why does using a straw reduce acid?
A straw doen't actually reduce the acid itself it only reduces the amount that touches and can harm your teeth.
Jorge has four liters of 30 percent acid solution how much water should he add to make 25 percent acid solution'?
Jorge needs to add 2 liters of water to the 30% acid solution to make a 25% acid solution. This can be calculated using a dilution formula: initial acid amount / final total amount = final acid concentration.
A chemist is making 200 L of a solution that is 62 percent acid He is mixing an 80 percent acid solution with a 30 percent acid solution How much of the 80 percent acid solution will he use?
The chemist will use 100 liters of the 80% acid solution and 100 liters of the 30% acid solution to make a 200-liter solution that is 62% acid. The amount of acid in the 80% solution will be 0.8 * 100 = 80 liters, and in the 30% solution, it will be 0.3 * 100 = 30 liters.
