A sugar solution contains 26g of sugar in 50 L of solution. What is the concentration in g L?
The concentration of sugar in the solution is 0.52 g/L.
What happens to concentration of the sugar solution as the water is removed?
Concentration increases
What is an Osmotolerant bacteria?
A microorganism that can grow in the presence of high sugar concentration
What will happen to dry apricots dipped in dilute of sugar solution?
If you dip dry apricots in a diluted sugar solution, the apricots will absorb some of the liquid. As the sugar solution evaporates, it will leave a thin layer of sugar on the surface of the apricots. This can slightly sweeten the apricots and make them slightly moister than they were before.
A 20.0-g sample of sugar is dissolved in 59.8 g of water. What is the concentration of the solution?
25 percent by mass
A sugar solution contains 26g of sugar in 50 L of solution. What is the concentration in g L?
The concentration of sugar in the solution is 0.52 g/L.
What happens to concentration of the sugar solution as the water is removed?
Concentration increases
What does a positive Benedict test indicate?
Benedict's solution is originally blue. Any change in color indicates presence of a reducing sugar. The intensity in color change is proportional to the concentration of the sugar. If there is enough sugar, the color changes from blue to green to yellow to orange to brick red.
How would you test an unknown solution for each of the following sugar fat starch protein?
Sugars - Benedict's solution Fats - Brown Paper Starch - Iodine Protein - Biuret Solution
What is an Osmotolerant bacteria?
A microorganism that can grow in the presence of high sugar concentration
What is the name of salt and sugar solution?
This is called concentration polarization.
Does conductivitiy of water change as concentration of sugar change?
No. Sugar solution is not an electrolyte because it has no free charges in the solution to carry the electricity.
What does Benedict's Test provide or test for?
Benedict's test estimates on color scale the presence of sugar .Normally used as a random pathological chemical test to determine the presence of sugar in urine in diabetes patients.In presence of sugar Benedict's solution turns from blue to shades of yellow,red,brown & dark according to the percentage of sugar present in solution on heating the solution.
What is the mass of 40g of sugar water?
This depends on the density of the solution and density depends on the concentration of sugar.
Formula for finding distance?
if the concentration of sugar solution of volume of 360 cm3 cube is 0.785 mol/ dm3 has the mass of 25g of sugar present in the solution. work out for the mole of the sugar content in the solution.
What indicator tests for sugar?
A simple test for testing sugar in a solution is by Benedict solution. Add Benedict solution to the solution on heat it will turn brick red or yellow depending upon its concentration.
How do you produce three solutions of sugar in water an unsaturated solution and a supersaturated solution?
Unsaturated, the sugar will dissolve and you won't see any sugar solutessaturated, when the solution has all the solutes that it can take and dissovledsuper saturated, there is too much sugar and you can see the sugar solutes
