How do you think bromothymol blue solution works?
Bromthymol Blue, when heated in a solution, indicates carbon dioxide. If there is carbon dioxide in the solution, it will turn bright yellow (when heated).
When a saturated solution of sugar and water is heated the solution becomes?
Supersatured.
Why reaction between zinc and hydrochloric acid be carried out in fume hood?
because it is exothermic reaction with heated products.
What kind of solution would an animal cell best survive in?
A solution with a pH of 7, heated to 96.8 degrees F.
When glucose is heated what substance turns orange red?
Benedict's solution, I believe.
Ammonia is always evolved when an ammonium salt is heated into a basic solution?
Yes, it is true.
Does it take longer to saturate a heated solution than a cold solution?
No, a heated solution will saturate faster.
What happened when saturated solution is heated?
It depends on what kind of solute was mixed in a solution. for example of NaCl, it would disolved if heated.
How do you make a yellow cake?
MESSAGE BEGINNING . ENTRY: YELLOWCAKE . REQUESTED: REFINEMENT FROM ORE . Carnotite is mined and treated with hydrochloric acid. The acidic aqueous layer is treated with a 10.5% solution of sodium hypochlorite to generate chlorine gas, and is then brought back to a pH of 0 with hydrochloric acid. Ammonium hydroxide is added and the solution filtered. The insoluble precipitate is put in a sodium carbonate solution and heated and once again filtered. The filtrate is brought to a pH of 3 with hydrochloric acid and then treated with hydrogen peroxide. The solution is filtered and the precipitate dried. Obtained is uranyl peroxide, a form of yellowcake as the precipitate from the last filtration. . MESSAGE END
Why is it essential for magnesium chloride solution in the crucible to be heated slowly?
If the solution is not heated slowly, the solution could boil over resulting in lost mass and calculation errors

Does sugar water have to be heated to create rock candy?
yes it has to be heated in water in a supersaturated solution.
What is the process which takes place when ammonium chloride is heated slowly?
Thermal dissociation, with the formation of ammonia and hydrochloric acid.
Why reaction between zinc and hydrochloric acid be carried out in fume hood?
because it is exothermic reaction with heated products.
What ds is left behind when a solution is heated?
When a solution is heated, the solvent usually evaporates, leaving behind the solute in a more concentrated form. This process is known as evaporation or drying.
Could hydrochloric acid cause an explosion and how?
Potentially, yes. Hydrochloric acid will react with most gases to produce hydrogen gas. Hydrogen is extremely flammable and can be very explosive if mixed with oxygen and heated.
