What is 2 drops of sodium chloride?
This depends on: - the volume of the drop - the concentration of sodium chloride solution
How would you test the presence of sulfate ions?
To identify the presence of sulfate ions in a solution, follow these steps: To acidify the sample, add a few drops of dilute hydrochloric acid (HCl) to the sample. Then, add a few drops of dilute barium chloride (BaCl2) solution to the sample. If sulfate ions are present in the solution, a white precipitate of barium sulfate (BaSO4) will form. The reaction is: Ba²⁺ (aq) + SO4²⁻ (aq) → BaSO4 (s) For example, if we have a solution of magnesium sulfate (MgSO4), the reaction would be: BaCl2 (aq) + MgSO4 (aq) → BaSO4 (s) + MgCl2 (aq) By observing the formation of the white precipitate, we can confirm the presence of sulfate ions in the sample.
If you water plants with a solution of honey and water does it affect the plant?
yes it does it can help the plant if you add a couple of drops of it
Why insert the dropper into the test tube when adding some drops of chemicals?

How do you test for the presence of chlorine in aluminium chloride?
The sample of aluminum chloride be treated with some ammonia(1:1)aqueous solution and filtered.To the filterate add a few drops of 2N HNO3, aqueous solution, followed by a few drops of 1% aqueous solution of silver nitrate. Appearance of curdy white precipitate soluble in dilute ammonia aqueous solution would indicate presence of chloride. Since aluminum chloride is quite covalent, the chromyl chloride test may not be very effective

How many gtt in 8 ml?
gtt stands for "drops" in medical terminology. you need to determine the type of solution [fluid] that you are refering to in order to determine the number of drops. So, for instance, a crystaloid solution [e.g. normal saline] has 20 drops per ml Therefore 8mls would form 8 x 20 drops = 160 drops A colloid solution should as [gelofusine or blood] has only 15 drops per ml therefore 8mls would form 8 x 15 drops = 120 drops Hope this helps.
What is an acid reaction?
If you have an acid of unknown strength, you add Universal Indicator & add drops of a base. Count the drops of the base until the solution turns green (neutral) This should tell you how strong the acid is. This can also be done the other way (with a base of unknown strength & adding an acid) Does that make sense?
