take 0.25 grams of
sodium hypochlorite
and dissolve it into 100 mls of water, put in a pH probe and add boric acid until the pH is about 8.0, which takes about 0.65 grams of boric acid
To make Eusol solution, dissolve 300g of sodium chloride (table salt) and 20g of calcium hypochlorite (bleaching powder) in 10 liters of water. Mix well until all the ingredients are fully dissolved. Eusol solution is commonly used as an antiseptic for wound care.
A concentrated solution can be weakened by adding more of the solution material (usually water) to dilute it.
Yes, you can make a 1N NaOH solution from a 0.1N NaOH solution by diluting it 10 times. For example, to make 1 liter of 1N NaOH solution, you would mix 100 ml of the 0.1N NaOH solution with 900 ml of water.
To make a 0.25N K2CrO4 solution, you need to first calculate the molecular weight of K2CrO4 (potassium chromate). Then, determine the grams of K2CrO4 needed to make the desired volume of solution at a concentration of 0.25N. Dissolve this amount of K2CrO4 in the required volume of solvent, usually water, to make the final solution.
To make a 0.1M solution of NaOH, dissolve the appropriate amount of NaOH pellets in water to make a solution of the desired volume. For example, to make 1 liter of 0.1M NaOH solution, dissolve 4g of NaOH pellets in enough water to make 1 liter of solution. Remember to wear appropriate safety gear and handle NaOH with care due to its caustic nature.
Two substances that make up a solution are a solute and a solvent. The solute is the substance that is dissolved in the solvent, which is the substance that does the dissolving.
Edinborough University SOLution
There are three English anagrams of the letters elosu – these are, the most common word, "louse", the word "eusol", which is a kind of antiseptic, and the word "ousel", meaning a blackbird.Of these, the word you are probably looking for is louse.
To make a solution, you add a solute to a solvent. The solute dissolves in the solvent, resulting in a homogeneous mixture where the solute particles are evenly distributed throughout the solvent.
Add water to the solution
When you are looking to make a potassium thicyanate solution you have to dissolve 0.972 g of KSCN in enough H2O to make a 100 mL solution.
No, evaporation will most likely make the solution supersaturated
It is the solution; sometimes also called the root.
concentrated solution
You have to Heat it!
Solute dissolves in solvent to form solution.
You need 6,9 mL stock solution.
A concentrated solution can be weakened by adding more of the solution material (usually water) to dilute it.
