What else can I help you with?
Glucose and I2KI inside the bag what color would be present in dialysis tubing bag experiment?
In the dialysis tubing bag experiment, if glucose and I2KI are present inside the bag, the color of the I2KI solution will turn blue-black due to the reaction of iodine with starch present in the glucose solution. This color change indicates the presence of glucose inside the bag.
What would happen if you did an experiment in which the iodine solution was placed in the Baggie and the starch was in the beaker?
The iodine solution in the baggie would diffuse into the beaker containing the starch. The iodine molecules would interact with the starch molecules, resulting in the formation of a dark blue or black color, indicating the presence of a starch-iodine complex.
What would happen if you added three drops of iodine to an onion?
I did this experiment and after a while the onion cell became incredibly easier to see.
How can you tell if osmosis occurred in dialysis tubing?
Osmosis is usually detected by simply looking at the experiment - most of the time, enough water is transferred to cause a noticeable rise/fall in water levels. However, I assume you could tell through the usage of weighing scales - as water re-distributes, as would the weight.
Why avoid the light in determine iodine value experiment?
Avoiding light in the determination of iodine value is important because iodine is light-sensitive and can react with light, leading to inaccurate results. Light exposure can cause the iodine to degrade or evaporate, which would affect the measurement of the iodine value. By conducting the experiment in a dark environment, you ensure the accuracy and reliability of the iodine value determination.
What would happen if there is less intake of iodine?
leads to goitre
What will happen if the variables in an experiment were not identified?
the experiment result would be confusing
What would happen if you hit iodine with a hammer?
If you were to hit iodine with a hammer, it would most likely shatter into small pieces or powder. Iodine is a brittle solid, and its crystal structure would break upon impact from the hammer.
Why an experiment must have control?
An experiment must have a control to show what would happen if no factors were changed.
What would happen if the iodine molecules passed through the membrane into the starch suspension?
The starch suspension would form into a blue-black precipitate. This is due to the reaction between starch and iodine.
What might happen to the brittle leaf if you tried to spread it on the white tile?
The iodine would then not spread.
What might happen to the brittle leaf if you tried to spread it out on the white tile?
The iodine would then not spread.
