Answer:
The correct answer is because distilled water has a neutral pH=7.
Explanation:
Distilled water has a neutral pH of 7, which means that water is neither an acid nor a base. Vinegar is a dilute acid that can be further diluted with water, or it can be neutralized using a base. The term "pH" means "hydrogen potential", the more hydrogen-free ions in flotation in a solution, the more acidic it will be.
The pH of vinegar will always be kept at a lower than neutral number, no matter how diluted, because vinegar is an acid.
By adding distilled water (pH = 7) to the vinegar, it does not increase the amount of H+ in the solution, so it does not affect the pH of the vinegar.
Have a nice day!
Answer:
a
n=m/M
mass if 85 gms and molar mass is 169.87 g/mol
85/169.87=0.50038 moles
Explanation:
Answer:
butan-2-ol
Explanation:
The reaction is of an alkene with water in acidic medium. This will give addition product where water will add on the alkene according to Markovnikov's rule.
However, as alkene is symmetrical,w we will get single addition product.
The steps will be
a) There will be protonation of alkene with the acid (the catatlyst), resulting in formation of carbocation.
b) the carbocation formed will be attacked by water molecule, following by deprotonation to give alcohol.
The reaction is shown in the figure.
Answer:
He will need a volumetric flask of 5ml and a volumetric pippet of 1ml.
You don't want to dilute it a lot becuase you can fall out of the limit.
I hope you find this infromation useful and interesting! Good luck!
