Starch does react with water it undergoes a hydrolsis reaction. Starch is composed of 2 different polymers - amylose and amylopectin, however for the reaction to occur you need the enzyme amylase - it breaks down amylose alot more efficiently than amylopectin but it will breakdown amylopectin.
amylose + (n-1) H2O --(Amylase)--> n Alpha Glucose
To break down starch in the lab - without enzymes I assume a concentrated acid catalyst (HCl or H2SO4) under reflux will most likely break it down however i'm not 100% because the connection between the glucose molecule is an ether group not an ester or amide. You'd have to try it yourself to confirm.
* You may have to reflux it though for 24hrs because you do for amides, and i'm pretty positive alkaline hydrolysis will not work.
What else can I help you with?
What does insolute mean?
It means a chemical/ substance, that cannot be dissolved in a liquid. An example would be starch and water, as starch is insolute when added to water.
Why doesnt super glue stick to the packet?
Because it has to react with oxygen in the atmosphere to harden.
What is the color of potato cell if added with iodine solution?
iodine is an indicator for starch, potatoes are basically starch storage organs for potato plants. that's why they are good to eat, mmm starch!
Starch is dissolved in which solvent?
Cold water. It is only slightly soluble in hot water. It is partially soluble in some organic liquids such as methanol and acetone.-----------------------------------N-methyl morpholine N-oxide (NMMO) is direct solvent for cellulose and other polysaccharides such as starch.
How does the shape of water affect its behavior?
water doesnt have a shape
How does copper react in water?
It doesnt
What metal doesnt react with acid or water?
Gold is a metal that does not react with most acids or water.
Does hot water react with aluminum?
No, hot water doesnt go through the foil
Will corn starch react with vinegar?
no
What substances in the bond paper does the iodine painted on the skin react?
starch starch
Would distilled water test negative for starch?
Yes, distilled water would test negative for starch. Starch can only be detected through specific chemical tests that involve reagents like iodine solution, which would not react with distilled water.
A metal used for piping because it doesnt react with water is?
Examples: lead, stainless steel, sometimes copper.
Is starch dissolve in water and why?
Starch consist of two types of natural polymers.NamelyAmylopectinAmyloseAmylopectin is water soluble but Amylose is water insoluble.this is reason why starch don't dissolve in water
What food doesn't react with iodine?
It's very likely that Iodine will react with plant products, since Iodine reacts with starch. Negative controls (glucose, water, and protein) could be used to verify the result.
Does H2O contain starch?
No. Water contains nothing but water. It can contain starch if starch is added to it.
What happens when glucose and starch react together?
Glucose and starch do not react together chemically. However, enzymes such as amylase can break down starch into glucose through a process called hydrolysis. This allows the glucose to be used for energy production in the body.
What is result when silver nitrate is added to a starch?
When silver nitrate is added to starch, no reaction occurs. Silver nitrate does not react with starch molecules.
