Why Gycerol is used for the titration of NaOH with Borax?
cuz' borax contain boric acid (H3BO3) which is very weak acid , thus it gives non accurate titration, so we add neutral glycerol to increase the acidity by the way we add glycerol after titration of NaOH not before
How borax acts as water softening agent?
When borax is added to hard water elements like Mg and Ca react with borax and come out of water and water becomes soft
What effect does glycerin have when you add to glue water and borax?
"Glycerol draws water from its surroundings and the heat produced by the absorption makes glycerol feel warm. Due to this property, glycerol is added to adhesives and glues to keep them from drying too fast. "--"Glycerol: A Jack Of All Trades" by Mary Ann David, George S. Henry Academy, North York (Toronto), Ontario
Is borax dangerous?
Borax, which is also known as sodium borate, disodium tetraborate, or sodium tetraborate is known as a cleaning booster and it also helps with odor control. It can be dangerous if used around chemicals it could react poorly with, or in an inappropriate manner.
Anhydride with ethylene glycol versus phthalic anhydride with glycerol?
You get a polymer! When you have ethylene glycol react with phtalic anhydride in a basic sollution such as NaOH(aq) you'll get a linear polymer. When you have glycerol react with phtalic anhydride in the same way you'll get a crosslinked polymer. The important difference between glycerol and ethylene glycol is the amount of OH groups, and as we all know, the OH groups usually the group that reacts - particularly in the creation of polymers. So in this case your crosslinked polymer will be the glycerol as it has 3 OH groups. One in each end, allowing the molycule to connect with other molecules and create polymers, and one in the middle (connected to the 2nd Carbon Atom) allowing it to react with other polymers. I hope that sort of answers your question

it makes pretend muccus (silivia)

What is the chemical reaction between borax and hot water?
In a starch-type glue (e.g. a wheatpaste glue / wallpaper glue), the borax acts as a gelling agent, thereby increasing the viscosity and glue strength. Borax also has fungicidal properties, thereby acting as a preservative against mould.
Give equations to represent the following reactions.(a) Borax is heated with CaO?
The chemical equation to represent the reaction between borax (Na2B4O7) and CaO (calcium oxide) when heated is: Na2B4O7 + CaO → CaB4O7 + Na2O In this reaction, borax and calcium oxide react to form calcium tetraborate (CaB4O7) and sodium oxide (Na2O) as the products.

Is borax in tide?
Tide does not contain borax as such but contain the same chemical as borax.
'why we use glycerol in estimation of boric acid in given sample'?
boric acid does not react with NaOH directly. When glycerol is added, the mixture behaves as monobasic and so it can be titrated with alkali using phenolphthalein
What color is glycerol?
Glycerol is colorless.
Is borax in tide detergent?
Tide does not contain borax as such but contain the same chemical as borax.
