Answer:

The solution turns purple because ammonia is a base.

The solution turned red.

Ammonia gas is neutral, but ammonia solution ( ammonium hydroxide ) is a base.

Adding vinegar to ammonia suppresses its dissociation hence decrease in hydroxyl ion concentration.

If more ammonia is added to the solution, the pink color re-appears.

Water _____.

Sergio039 [100]

Answer: is neither an acid nor a base

Explanation: Water is a universal solvent which means it can dissolve most of the substances in it.

Water has high thermal heat capacity , which means large heat is required to heat the water.

Water is not always pure as it gets contaminated by various pollutants present in the atmosphere such as gases, bacteria and suspended matter.

Water is an amphoteric substance which can act as both acid and base, thus can donate and acept [texH^+[/tex] ions.Thus it is neither an acid nor a base.

$HCl+H_2O\rightarrow H_3O^++Cl^-$

Here water is accepting a proton, thus it acts as base.

$NH_3+H_2O\rightarrow NH_4^++OH^-$

Here water is donating a proton, thus it acts as acid.

Why is it important to read a volume measurement using a graduated cylinder at eye level on the lab bench top verse just holding

Afina-wow [57]

<span>Measuring with a graduated cylinder is complicated somewhat by a meniscus. A meniscus is the curvature of the surface of the water. Water "sticks" to the walls of the graduated cylinder, but only on the sides and not the middle.
