1) A conductivity apparatus is not that useful in separating acids from bases because both solutions conduct electricity. True or false

2)The hydronium ion contains a water molecule bonded to a hydrogen ion. True or False

true

1) True, because both acids and bases can conduct electricity due to the presence of ions in their solutions. So, a conductivity apparatus won't help in separating them based on their conductivity.

2) False, the hydronium ion (H3O+) consists of a water molecule with an extra proton (hydrogen ion, H+) attached to it. So, it's like a water molecule with a clingy hydrogen ion friend.

1) False

To determine the usefulness of a conductivity apparatus in separating acids from bases, we need to consider the conductive properties of acids and bases. Acids are substances that release hydrogen ions (H+) in solution, while bases are substances that produce hydroxide ions (OH-) in solution. Both of these ions can conduct electricity. However, the ability to conduct electricity also depends on the concentration of ions in the solution. Strong acids and strong bases, which dissociate completely in solution, will have a higher concentration of ions and thus higher conductivity. On the other hand, weak acids and weak bases have lower concentrations of ions and lower conductivity.

In the case of a conductivity apparatus, it measures the electrical conductivity of a solution. Since both acids and bases can conduct electricity to some extent, a conductivity apparatus can be useful in distinguishing between strong and weak acids or bases by comparing their conductivities. This can aid in the separation of acids and bases based on their strength.

2) False

The hydronium ion (H3O+) is a positively charged ion that forms when a water molecule (H2O) acquires an extra proton (H+). In other words, it consists of a water molecule bonded to a hydrogen ion that has gained an additional proton. The presence of the extra proton gives the hydronium ion its positive charge.

So, to reiterate, the statement that the hydronium ion contains a water molecule bonded to a hydrogen ion is true.
