The concentration of alcohol and water solution is 25 percent alcohol by volume what is volume of alcohol and 200 lM of solution?
If the concentration of alcohol and water solution is 25 percent alcohol by volume, the volume of alcohol in a 200 solution is 50.
When water is added to a blue solution of copper sulfate the solution changes to a lighter shade of blue Is this an example of a chemical reaction?
If the water being added is pure, and the solvent in the copper sulfate solution was water, then no, this should not result in a chemical reaction. The visual change is due to dilution of the solute
A biochemist wishes to dilute 75 ml of an aqueous 3.5 M H2SO4 solution to an aqueous 2 M H2SO4 solution. How much water should be added to the solution?
30 mL water.
How do you calculate dilutions?
H! Refer below to the formula of dilution: C1V1 = C2V2 Sample problem: How much water and how much 12 M HCl must be used to prepare 500 ml of a 1 M HCl solution? # Determine the volume of 12 M to be used using the dilution formula (12) (volume of 12 M) = (1) (500) volume of 12 M = (1) (500) / 12 = 41.7 ml 12 M # Determine the volume of water to add to it Total volume after dilution = volume of 12 M + volume of water added 500 = 41.7 + volume of water added 500 - 41.7 = volume of water = 458.3 ml of water to be added to the 41.7 ml of 12 M Regards, Dianne
What ingredient pepper or salt forms a solution with water?
Salt forms a solution when added to water.
How much water should be added to 3 gallons of pure acid in order to obtain the 15 acid solution?
You need 17 gallons for a 15% volume/volume mixture.
What is produced when water is added to water?
Nothing is "produced". You have merely increased the volume of water. You have not diluted it, and you have not formed a solution.
What is the percentage of volume?
Volume percent (v/v %) is defined as: volume percent = [(volume of solute) / (volume of solution)] x 100% Volume percent is handy when preparing solutions of liquids. Concentration of a solution can be stated in volume percentages. Be aware that volume of solution is in formula denominator, not volume of solvent. Thus to get 10% v/v solution of ethanol in water you can take 10 ml of ethanol and add enough water to have total 100 ml of resulting solution. It is worth to mention volumes of solute and solvent cannot be simply added to get volume of solution. For instance if you add 10 ml of ethanol to 90 ml of water the volume of the solution will be less than 100 ml.
The concentration of alcohol and water solution is 25 percent alcohol by volume what is volume of alcohol and 200 lM of solution?
If the concentration of alcohol and water solution is 25 percent alcohol by volume, the volume of alcohol in a 200 solution is 50.
What changes occcur with the water level if any as more and more sodium chloride was added to the solution?
The total volume is a little decreased.
An oral suspension contains 8gm of medication in 200ml of solution so How many milligrams are in each teaspoon dose?
200 ml of solution is 40.5768271 teaspoons. Ignoring the volume of the 8gm of medication, each teaspoon would have 8gm/40.5768271 = 0.197156864gm = 197.156864 milligrams of medication. Note that we ignore the volume of the medication because (i) we don't know the exact volume of the medication, and (ii) we don't know to what extent it changes the overall volume of the solution when added to it (a cup of water with a teaspoon of sugar added to it, for instance, has the same volume (although more weight) as the the water before the sugar was added - the molecules of sugar slip into the empty spaces between the water molecules).
Why does the volume change when added to water?
this is because water is having its own volume.
When water is added to a blue solution of copper sulfate the solution changes to a lighter shade of blue Is this an example of a chemical reaction?
If the water being added is pure, and the solvent in the copper sulfate solution was water, then no, this should not result in a chemical reaction. The visual change is due to dilution of the solute
Why does the volume of sugar solution remain same but the weight increases?
The volume of the resulting solution is actually increased. As a rule of thumb the extra volume is about 60% of the kg mass taken in litres.Example: 1 L water + 1 kg sugar will take 1 L + 0.60L = 1.6 L(with total mass of 2 kg solution)

How do you dilute 20 volume hydrogen peroxide to make a 3 percent solution?
20 volume is 6% solution. To make it 3% solution just add same volume of water to the original 6% solution and you have double volume of 3% solution.
