Answer to Question #55514 in General Chemistry for joe

Question

All the following apparatus are needed for the preparation of a solution of hydrochloric acid, HCl, from the concentrated solution EXCEPT --------------.
Measuring cylinder
Burette
Crucible
Volumetric flask

If
15cm3
of 10.25M HCl solution is made up to volume in a 500 Ml volumetric flask, what will be its new concentration?
0.306M
3.06M
5.13M
0.52M

In the preparation of a solution, it is advisable to shake the mixture well. This is necessary to ----------------.
Ensure that the solution precipitates out very well
Induce air bubbles in the solution
Produce a homogenous solution
Facilitate use of lesser volume of water

To dilute an acid with water, acids are added to water and not water to acid because -----------------.
Acids are more vicourse than water
Water is weaker than acid
Dissolution of acid in water is exothermic which could be explosive
Acids will not dissolve in water if done wrongly

Answer 1

burette
0.306 M
Produce a homogenous solution
Dissolution of acid in water is exothermic which could be explosive
