It usually takes approximately 4 drops.
There are approximately 240 drops in 10 ml. Therefore 2.5 ml contains about 60 drops.
"Drops" come in many different sizes (the biggest raindrops have as much water as a thousand of the smallest raindrops and the smallest raindrops are a million times as massive as the typical cloud or fog droplet). However, some old cookbooks reckon that there are 72 drops to a teaspoon and there are roughly 200 teaspoons to the liter, so 14,400 drops per liter is a pretty close answer. You could call it 15,000 and not be far wrong.

for most fluids it takes about 10 drops to equal 1 ml 1 fluid ounce (US) equals 29.56 ml or about 296 drops so 1000 drops is about 3. 35 fluid ounces more or less.
i have always been told 20 drops per ml is rule of thumb, i am a certified pharmacy technician, and that is what we go by when dispensing medication It, of course, depends on factors like type of solution, temperature, viscosity, etc. (All of which are, yes, taught to all students in pharmaceutical classes) The typical "rule of thumb" is 20 drops/ ml for low viscosity liquids, such as water.
Ammonia gas get dissolved in water which form ammonium hydroxide. NH4OH is alkaline in nature. so when phenolphthalein is added to it. It produce PINK colouration.
One common way to test for ammonia is by using ammonia test strips or a liquid reagent test kit. These kits typically involve collecting a water sample and adding a few drops of the test solution to detect the presence of ammonia based on a color change. It is important to follow the instructions provided with the test kit for accurate results.
Hydrochloric acid will turn pH paper red or pink when a few drops are added. This color change indicates that the acid is acidic, with a pH typically below 4.
Ammonia is present in the human body and converted into urea by the liver. Those with liver problems can have too much ammonia in the body thus developing potentially dangerous illness.
Iro Eye drops are not a real product. They do not exist.. unfortunately. The site is also a fake. If you watch the "Commercial for it on Youtube you can see how the chicks eyes change without here even putting the eye drops in, so what is stopping them from making the eye change after the drops are put in the eye making it look like they made the color change. In the Commercial she is using Rohto eye drops.. Google it :-/ Sorry dude, they are not real
Sometimes Cichlids change color when the temperature of the tank drops or rises suddenly. From my experience. -Alan Armour
Starch turns a blue-black color when treated with a few drops of iodine solution. This color change occurs due to the formation of a complex between the starch molecules and the iodine ions.
If you mix albumin with 5 drops of biuret reagent, the resulting color would most likely be a purple hue. This color change occurs due to the presence of peptide bonds in the protein, which react with the biuret reagent to form a colored complex.
first do a water test for pH and ammonia if the ammonia is high like over 0 ppm like 2ppm do a 25% change if the ammonia is high and add a water treatment like stress coat to lower the ammonia now the pH the pH need to be 7 to 8 if its not in that range you add some drops that you would find in your test kit to raise the pH then test water to see if the pH is ok
If you add iodine drops to a non-starch substance, such as sugar or protein, there will be no color change. Iodine is used to detect the presence of starch by turning blue-black in the presence of starch molecules. Non-starch substances will not produce this color change.
You can test for starch in a seed by using iodine solution. Add a few drops of iodine solution to the seed and observe for any color change. A blue-black color indicates the presence of starch in the seed.
I make Danish Christmas cookies and need bicarbonat of ammonia for one of the recipies. I have not been able to find in in any grocery store. However, Ammonium Carbonate (Drugstore) and a couple drops of vinegar will function well. Most drugstores also have bicarbonate of ammonia :-)!
