What happens when iodine is added to starch and distilled water?
As you know that iodine act as indicator for testing of starch so when a drop of iodine is added to starch it turns bluish black but when added to distilled water nothing happens except the colour of water which turns brown and its is the colour of iodine.
Add a drop of iodine to both a distilled water test tube and to the test tube containing the starch solution in the test tube What do you observe?
The starch solution will turn black, while the distilled water will remain brown, the same colour as the iodine. This is actually because water, normally used as a control, does not contain any starch and as we know, the iodine test is highly specific for the presence of starch hence no colour change other than iodine dissolving in water to form an iodine solution contrary to starch which we know complexes with iodine, to form starch-iodine complex forming the blue-black colour observed
If you used distilled water instead of alcohol in a gram staining procedure what would be the colour of gram positive and what of gram negative bacteria?
If we use distill water in gram staining instead of alcohol then both gram +ve and gram -ve will appear blue as distilled water is not able to remove crystal violet from cell wall and so when we counter stain the cell with safranin it will give no effect of that and cell show only blue colour
Which has a higher water potential red blood cells or water?
Distilled water would have a higher water potential than a red blood cell because the formula for obtaining water potential is -iCRT, where i=ionization constant, C=molar concentration, R=pressure constant--usually 0.0831 liter bars/mole K, and T=temperature in Kelvins. Since distilled has a molar concentration of 0, the water potential would be 0. And a red blood cell would have a negative water potential because it does have some sort of molar concentration. Thus, distilled water would have a higher water potential because 0 is greater than a negative number. As a note, water always flows from areas of higher water potential to areas of lower water potential. Therefore, it is easy to imagine that water flows toward more concentrated solutions, meaning it would flow to the red blood cell. If distilled water flows to the red blood cell, then it must have a higher water potential than the red blood cell.
Can distilled water kill you if consumed in large quantities?
Yes, consuming large quantities of distilled water can lead to water intoxication, which can be fatal.

How can you tell if glucose starch water and iodine passes through the cell membrane?
If the glucose, starch, and iodine pass through the cell membrane, you can perform a color change test. The presence of glucose will show a positive result with Benedict's reagent turning orange/red. The presence of starch will show a positive result with iodine turning blue/black.
What are the contents of starch agar?
:D Beef extract (3.0g) Soluble Starch (10.0) Agar (12.0) Distilled water (1,000.0 ml)
Does distilled water contain glucose?
Distilled water is close to pure water, and if it was distilled in a clean environment it would be pure water. Thus no, it would not have maltose ( a sugar) in it.

When growing sugar crystals in tap water or distilled water how would you start your variable?
distilled water
What does it mean to say distilled water is neutral?
It carries neither a positive or negative charge.
Why do you have to test starch sugar and distilled water seperately?
Testing starch, sugar, and distilled water separately helps to establish baselines for comparison. This ensures that any observed changes in the results are due to the specific substance being tested rather than external factors. It helps in accurately determining the reactions and properties of each substance.
How starch can give a negative iodine test?
Starch can give a negative iodine test when starch is mixed with iodine in water. The iodine gets stuck in the coils of beta amylase molecules and the starch forces the iodine atoms into a linear arrangement in the central groove of the coil.
Distilled water pure substance?
You may regard distilled water as a pure substance. Common salt would be another, as would refined sugar.
Are there any difference between distilled water used for batteries and distilled water used for terbine washing?
No, distilled water is distilled water.
How would you make oobleck if you don't have cornstarch or tapioca starch?
You would use potato starch and water
