Beryllium Hydroxide Solubility Concepts

The video explores the solubility of beryllium hydroxide (BeOH2) in water. Initially, it discusses general solubility rules, noting that most hydroxides are only slightly soluble, with exceptions like lithium, ammonium, and sodium hydroxides. The video then examines a solubility table, which is inconclusive for BeOH2, leading to the conclusion that it is slightly soluble or insoluble. For net ionic equations, BeOH2 is considered insoluble due to its minimal solubility.

What is the general solubility rule for most hydroxides?

• Most hydroxides are highly soluble.

• Most hydroxides are slightly soluble.

• Most hydroxides are completely insoluble.

• Most hydroxides are insoluble.

Which of the following hydroxides is an exception to the general solubility rule?

• Beryllium hydroxide

• Lithium hydroxide

• Calcium hydroxide

• Magnesium hydroxide

What does the solubility table indicate about beryllium hydroxide?

• It is highly soluble.

• It is insoluble.

• It is slightly soluble.

• The table provides no clear answer.

Why is the solubility table not helpful for beryllium hydroxide?

• It does not mention beryllium hydroxide.

• It lists it as insoluble.

• It lists it as highly soluble.

• It shows a question mark.

Which ion does beryllium form in the solubility table?

• Be3+

• Be2+

• Be1+

• Be0

For net ionic equations, how is beryllium hydroxide considered?

• Highly soluble

• Completely soluble

• Slightly soluble

• Insoluble

What is the final conclusion about the solubility of beryllium hydroxide?

• It is highly soluble.

• It is not soluble at all.

• It is slightly soluble or insoluble.

• It is completely insoluble.
