Question
During your future endeavors in chemistry you will inevitably do a bunch of acid- base problems. Of the strong bases above , calcium hydroxide strontium hydroxide, and barium hydroxide often trick students into making small mistakes. Why do you think that is the case? Nothing special about these , all acid-base is confusing! There are two moles of hydroxide for each mole of these compounds. ) There is only half a mole of hydroxide per mole of compound. They are actually acidic rather than basic.

Answer
### B. There are two moles of hydroxide for each mole of these compounds.
Explanation
## Step1: Identify the nature of the problem### The problem is about understanding why calcium hydroxide, strontium hydroxide, and barium hydroxide often confuse students in acid-base chemistry.## Step2: Analyze the given options### The options provided are:1. Nothing special about these, all acid-base is confusing!2. There are two moles of hydroxide for each mole of these compounds.3. There is only half a mole of hydroxide per mole of compound.4. They are actually acidic rather than basic.## Step3: Evaluate each option### Option 1 is a general statement and does not address the specific confusion.### Option 2 is correct because calcium hydroxide, strontium hydroxide, and barium hydroxide are all strong bases that dissociate to give two moles of hydroxide ions (
) per mole of compound.### Option 3 is incorrect because it contradicts the chemical properties of these compounds.### Option 4 is incorrect because these compounds are bases, not acids.## Step4: Conclude the correct answer### The confusion arises because there are two moles of hydroxide for each mole of these compounds.#
