Is water more viscous than honey?
the intermolecular attractionsis account for this behaivour of honey.
Which is more viscous pure water or saline water?
Saline water is more viscous than pure water because the presence of dissolved salts increases the resistance to flow, making it thicker. This higher viscosity can be attributed to the interaction between the salt ions and water molecules, creating more friction as the liquid moves.
Why is water better than ethanol for chromatography?
Water is preferred over ethanol for chromatography because it is more polar and can interact with a wider range of compounds, providing better separation. Additionally, water is a safer and more environmentally friendly solvent compared to ethanol.
What is the difference of absolute ethanol to the regular technical grade ethanol?
technical grade is bethween 96% and 98% ethanol and ethanol absolute means pure ethanol whithout water ('almost') 99.9% ethanol Absolute ethanol has no water whereas 96% ethanol has 4% water or 98% has 2% water. Thus, the reaction can occur with water.
Does ethanol contain water?
Yes, ethanol can contain water as it is a common impurity in ethanol. Ethanol is a type of alcohol that can be mixed with water.
Is water more viscous than vegetable oil and methylated spirits?
Water is more viscous than methylated spirits, and vegetable oils are more viscous than water.
Is water more or less viscous than spirits?
Ethanol has dipole moment in the C-O bond and the carbon part of it has London Disperse force, whereas water has only hydrogen bond. So ethanol has more intermolecular force than water, making it more viscous than water. Meanwhile, ethanol has less boiling point than water because London disperse force is easily disrupt by heat.

Which liquid expands more Ethanol or Water?
Ethanol expands more than water when heated because it has a higher coefficient of thermal expansion. This means that ethanol will increase in volume more than water when heated to the same temperature.
What is meant by a viscous liquid?
Viscosity is a measure of the thickness or how runny a liquid is. More viscous means thicker and syrup-like. Less viscous means more runny and more like water.
Can a viscous fluid be less dense then fresh water?
Yes, for example oil is less dense than water even though it is more viscous.
Why ethanol viscosity increases after 50?
because of the intermolecular forces.at 50% the OH ions of ethanol and OH ions of water are maximum and they interact while after this % the viscosity of ethanol itself starts dominating as the pure ethanol is less viscous so viscocity goes on decreasing!
Explain.Glycerol is more viscous than ethanol?
By definition, to overcome viscosity we need to apply enough kinetic energy to overcome the intermolecular forces of attraction of a substance. The harder it is to overcome this, the more viscous the substance is. And we all know that hydrogen bonds are the toughest intermolecular bonds to break. This being said if we look at the ethanol molecule it has one hydrogen bond to ether's none. Therefore, more kinetic energy would be required to overcome the attractions by that bond thus increasing the average kinetic energy needed by the substance to overcome or reduce its viscosity.

Why is water a better conductor than ethanol?
Water is a better conductor than ethanol because it contains ions that can move freely and carry electrical charges, while ethanol does not dissociate into ions as readily. This means that water can facilitate the flow of electricity more easily than ethanol.
