How much water must be added to one liter of a 5 saline solution to get a 2 saline solution?
If it is 5 molar: 5 moles per liter, then you start with 5 moles of salt. You will always have 5 moles of salt, but it is spread among a bigger volume.
So you want it to be 2 moles per liter, so the amount of salt is 2*V, but we know that there are 5 moles, so we have 2*V = 5, and V = 5/2 = 2.5 Liters. Since we started with 1 liter, we must add 1.5 liters.

A chemist wants to make a 10 solution of fertilizer. how much water and how much of a 30 solution should the chemist mix to get 30 L of a 10 solution?
30 liters of a 10 % solution of fertilizer has .1(30) = 3 liters of fertilizer 1 liter of 30% solution has .3 liter of fertilizer 10 liters of 30% solution has 3 liters of fertilizer so, the chemist needs 10 liters of the 30% solution and 20 liters of water to make 30 liters of a 10% solution.
How much water must be added to 12 grams of a 90 percent iodine solution to produce a 25 percent iodine solution?
12*(90%)=10.8=X*.25 10.8/.25=X=43.2 43.2-12=31.2 31.2 grams of water must be added
How much water should be added to 1 gallon of pure antifreeze to obtain a solution that is 35 and 8203 antifreeze?
Approx 1.86 gallons.
How many liters of water must be added to 7 liters of a 20 percent acid solution to obtain a 10 percent acid solution?
7 liters of a 20% acid solution consists of 1.4 liters of acid (20% of the total volume) mixed with 5.6 liters of water (80% of the total volume). The amount of acid isn't going to change in the new solution. You are just going to add enough water to make it a 10% solution instead of a 20% solution. So it will be more dilute. That means that 1.4 liters of acid will represent 1/10 of the volume of the new solution. So the total volume of the new solution will be 10 x 1.4 or 14 liters. The amount of water in the new solution will be 14 - 1.4 = 12.6 liters. That is a difference of 12.6 - 5.6 = 7 liters from the amount of water you started with. So you need to add 7 liters of water to the original 20% solution to make it a 10% solution. This makes sense because if you double the amount of the mixture from 7 liters to 14 liters and the amount of acid is unchanged, the solution will be half as strong.
How many liters of water must be added to 30 liters of 20 percent ALCOHOL solution to dilute it to a15 percent solution?
You have 6 litres of alcohol in 24 litres of water You need to add x litres to make 6 equal to 15% of 30 + x. 6 is 15% of 40, so x = 10
How much sodium chloride must be added to one liter of water to make normal saline?
To make normal saline, you would need to add 9 grams of sodium chloride to one liter of water. This is equivalent to approximately 0.9% saline solution.
What type of solution is salt on water?
When salt is added to water, it forms a homogeneous solution, meaning the salt particles dissolve evenly throughout the water. This type of solution is called a saline solution.
What does liquid water turn in to when heat is added?
A saline solution is formed.
When NaCl is added to water the solution will have what?
The chemical and physical properties are changed.
What is Sodium chloride 0.9 percent?
This is an isotonic saline solution; 9 g/L sodium chloride solution in water with added glucose.
What type of solution is saline solution?
Saline is a homogenous solution of salt in water.
Why is ti advisable to use normal saline solution rather than water?
Not sure what you are using saline solution for but i would say that saline solution is steril and water is not.
What a solution of salt and water?
saline solution
Is Saline NaCl?
Not exactly. Saline solution is sterilized and is a dilution of sodium chloride (NaCl) - meaning that the NaCl is dissolved in deionized water. The solution is 9 grams of sodium chloride (NaCl) dissolved in 1 liter of water.
Is saline a solvent water solution?
No, saline is a solution made by dissolving salt in water. In this case, water is the solvent.
Are normal saline solution and sterile water solution the same?
No, normal saline solution contains salt (sodium chloride) dissolved in water, while sterile water solution is pure water without any added salts or other substances. Normal saline is commonly used for medical purposes such as IV fluids or wound cleansing, while sterile water may be used for specific procedures where electrolytes are not needed.
Is saline solution a basic?
No, saline solution is not a basic solution. It is a neutral solution composed of a mixture of sodium chloride (salt) and water.
