Why does the temperature of tea decreases on adding sugar?
the heat may absorbed by the glucose particles of sugar dissolved..
What is the molarity of a solution containing 15.0g of aspartame dissolved in water and the solution volume is brought to 250.00mL by adding water?
The molarity is o,2.
What effect will adding the ice to the solution have on the amount of salt that can be dissolved into it?
The effect is unpredictable because the ice changes two variables at the same time.
What is concentration?
A concentrate is a dissolved substance in a solution. the strength of which can be increased by adding more of it or by evaporating the solvent i which it is dissolved.
What is the procedure for the standardization of sodium thiosulfate?
Thiosulfate can be standardised by adding excess potassium iodide solution to a known volume of a standard acidified solution of potassium dichromate, and then titrating the liberated iodine against the sodium thiosulfate solution.http://www.meduniv.lviv.ua/files/kafedry/tokshim/English/Analytical/Manuals_Analytchem/Iodometry.pdf
Why is NaOH heated before adding BaCl2?
By adding HCl, you can ensure the presence of the SO4(2-) ion.

How do you prepare 0.02 n iodine solution?
2.538g in 1000ml. If you are making this for a titration, like for SO2 or thiosulfate, you need also to add iodide: 1. dissolve 8 g potassium iodide in about 250 mL water. 2. add 2.538 g iodine to the water solution. Stir until dissolved. 3. transfer to a 1000 mL volumetric flask and Q.S. to 1000 mL You should standardize vs. thiosulfate or arsenious oxide.
Does the water level rises when sugar is dissolved in water?
Adding matter to matter with always increase overall volume

When does a solution become a saturated?
when the solute you are adding to the solvent will no longer dissolve any further i hope this helps :)
