How is iodine estimated in ccl4 and h2o layer?
Titrate each solution separately with solution of known concentration of sodium thiosulphate. The titre value will give the amount of thiosulphate reacted with iodine, hence you can find concentration of iodine.
Benzoic acid plus NaOH plus iodine?
C6H5COOH + NaOH + I2 -----------> C6H5COOI + NaI + H2O
What is water-water bonds called in a beaker of water?
The bonds beween the water molecules, H2O, are called hydrogen bonds.
What is the equation for iodine mixed with glucose?
I2(l) + H2O(l) -> OI-(aq) + 2H+(aq) + I-(aq)
Will a reaction take place if Ca H2O?
Yes. The reaction would be Ca + H2O --> Ca(OH)2 + H2. Hope that helped.
Is iodine in H2O?
No. H is hydrogen. O is oxygen. I is iodine. So this formula contains only hydrogen and oxygen.
What is the difference between beaker and graduated cylinder in terms of measuring a volume of liquid?
beaker holds the H2o been measured by the graduated cylinder
Differences between lugols iodine and grams iodine?
Lugol's Iodine = 20g Potassium Iodide + 10g Iodine dissolved in 1L H2O Gram's Iodine = 6.7g potassium iodide + 3.3g Iodine dissolved in 1L H2O Recipe's taken from Flinn Scientific Catalog I have on campus. Looks to me as Gram's is just a dilute version of Lugol's. Same ratio of KI:I just less of it. Couldn't tell you much about differences in application however.
Is it possible for two atoms of the same element to have different chemical properties?
Yes. In the case of isotopes of water. An H2O ice cube is shown to float in a beaker of liquid water, while an ice cube of D2O (heavy water) is shown to sink in liquid water.

Where does H2O take place in?
New Zealand
What can be known about a density of an object greater than h2o?
You can deduce that, if the object was in the form of of a solid "blob" it would not float on water.
Where does the tv show H2o take place?
Australia
In a beaker sugar is dissolved in water and then the water is heated and evaporates The sugar is recovered and heat is again applied Vapor is released and the material in the beaker changes from?
In a beaker, sugar is dissolved in water, and then the water is heated and evaporates. The sugar is recovered, and heat is again applied. Vapor is released, and the material in the beaker changes from white to black. What must you know to determine if a chemical change occurred? CO2 (carbon dioxide) CuO (oxidized copper) H2O (distilled water) H2O2 (hydrogen peroxide) NaCl (sodium chloride)
