Does salt dissolved in water change the number of drops that will balance on a coin?
Yes, adding salt to water increases its density, which may affect the surface tension of the water and impact the number of drops that can balance on a coin. The increased density can lead to smaller drops forming, potentially allowing more drops to balance on the coin due to the altered properties of the saltwater solution.
What is 2 drops of sodium chloride?
This depends on: - the volume of the drop - the concentration of sodium chloride solution
When a small amount of white powder was shaken with distilled water in a test tube powder sank bottom when drops of universal indicator were added it turn red?
The white powder is likely to be a base as it sank to the bottom when mixed with distilled water. The red color observed after adding universal indicator indicates that the solution became acidic. This suggests that the white powder was an insoluble base that released a basic solution when mixed with water, which turned acidic upon adding the indicator.
What is the three steps in performing chemical test for sugar and starchand able to conduct these test?
The three steps in performing a chemical test for sugar include 1) adding a few drops of Benedict's solution to the sample and heating it in a water bath, 2) observing the color change (from blue to green, yellow, orange, or red) if reducing sugars are present, and 3) comparing the color change to a reference chart. For starch, the steps involve 1) adding a few drops of iodine solution to the sample, 2) observing a color change to blue-black if starch is present, and 3) comparing the color change to a reference chart. Conduct these tests by following the steps mentioned using the appropriate reagents and samples in a laboratory setting.
Why insert the dropper into the test tube when adding some drops of chemicals?
Inserting the dropper into the test tube ensures that the drops of chemicals are accurately delivered into the solution without spilling or causing contamination. It also helps in controlling the amount of chemical being added, making the process more precise and reproducible.
Is eye drops a solution or suspension?

How is sodium chromate prepared?
Sodium chromate is prepared by adding caustic soda to Sodium Dichromate. Go on adding causting soda till the pH drops to 6. what we get is the solution of Sodium chromate and you can evaporate, crystallise and filter.
How many drops are in 3 milliliter?
~60 drops solution: 20 drops/mL * 3 mL = 60 drops
How is the pH of a solution is measured using universal indicator?
The pH of a solution is measured using universal indicator by adding a few drops of the indicator to the solution and observing the color change. The color of the solution corresponds to the pH level on the universal indicator color scale, which ranges from red (acidic) to purple (neutral) to blue (basic).
How many drops of ciprofloxacin hydrochloride ophthalmic drops solution do you used at a time for pink eye?
yes

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.
How can you identify Sulphate anions in a unknown solution?
Dip a copper coin in that unknown solution And make that solution slightly acidic. After about one hour, take out the copper coin and if there are green colours deposits then there is sulphate, otherwise not.
