What is the colour of methyl orange in alkaline medium?
the color of methyl orange in an acidic medium is orange
Difference between methyl cellulose and ethyl cellulose?
Cellulose has 3 hydroxyl (OH) groups on each glucose unit. Methyl cellulose replaces these hydroxyl groups with methoxy (OCH3) groups. Therefore it follows that these groups are now replaced with ethoxy groups or (OCH2CH3) groups.
What colour is methyl yellow when it reacts with an alkali?
Methyl yellow is yellow in alkaline medium.
Which is the best viscosity agent Sodium Carboxy methyl cellulose or Calcium Carboxy methyl cellulose?
Sodium Carboxymethyl cellulose will be better viscosifier as compared to calcium carboxymethyl celluose.Since during washing process sodium chloride will be removed as impurities therefore leading to pure Na CMC with viscosity depending upon the molecular weight of wood pulp or cotton linter.
How does methyl stearate compare to methyl oleate?
Methyl stearate is a saturated fatty acid methyl ester, while methyl oleate is an unsaturated fatty acid methyl ester. Methyl oleate has a higher degree of unsaturation due to a double bond in its carbon chain, making it more flexible and less rigid than methyl stearate. Additionally, methyl oleate may have different physical properties, such as a lower melting point, compared to methyl stearate.
What is Difference between Methocel and HPMC E5?
METHOCEL is a well known trademark of The Dow Chemical Company manufacturing cellulose ethers for various industries. Methocel is a trademark for methycellulose whereas HPMC E5 is Hydroxypropyl Methyl Cellulose with very low viscosity of 5 CPS (centipoise) used as rheology modifier as well as water retaining agent for film formation, synthetics adhesives as well as tablet coating. It has excellent water retaining properties. Samsung fine Chemicals, SE Tylose are one of the competitors of The Dow Chemical Company in the global market along with many Chinese companies.
What is tylose powder made of?
Methyl hydroxyethyl cellulose (MHEC) or Methyl hydroxypropyl cellulose (MHPC). This is a modified form of cellulose, which is naturally present in plants. When methyl groups and hydroxy groups are added to cellulose, the cellulose becomes easier to dissolve in water and from a gel.
What is the colour of methyl orange in alkaline medium?
the color of methyl orange in an acidic medium is orange
Why is cellulose used in ice cream?
Methyl cellulose is used to thicken ice cream
Difference between methyl cellulose and ethyl cellulose?

Will methyl-cellulose show a false positive on a drug screen?
yes
What colour is methyl yellow when it reacts with an alkali?
Methyl yellow is yellow in alkaline medium.
Is avicel and carboxy methyl cellulose same?
Avicel is crystalline cellulose, whereas cellulose is soluble cellulsoe, which is synthesized by the alkali-catalyzed reaction of cellulose. Endocellulase works at CMCase wheras, the exocellulases work dominantly at Avicel.
Why add methyl cellulose to a wet mount with living Paramecium cells?
slows down the organism and makes them easier to observe under a microscooe
Is methyl cellulose gluten free?
It can be derived from wheat but also from other ingredients such as corn, cotton or wood pulp. If you are gluten sensitive or a celiac you may need to avoid cellulose if you have a reaction. It can be in medicine, vitamins and it is even used as am anti caking agent in cheese.
What ingredients are used in KY gel?
I belive that KY intense gel is to make your sex life more intense while in bed.
What solvents can be used for cellulose ethers?
Methyl Acetoacetate can be used as solvent for cellulose ethers. It is a starting material for the syntheses of alpha-substituted aceto-acetic esters and cyclic compounds, e.g. pyrazole, pyrimidine and coumarin derivatives. Methyl Acetoacetate is a colorless, clear liquid with an an ester-like odor. It is used in chemical synthesis and is not sold directly to the consumer, therefore the workplace is the most likely place for potential exposure.
