Questions: PbBr2 soluble insoluble Ni(OH)3 soluble insoluble Bi(NO3)3 soluble insoluble

Transcript text: CHM -101 Class Resources Topic 6 Prelab 1 Question 3 of 11 (1 point) | Question Attempt: 1 of 1 $\mathrm{PbBr}_{2}$ soluble insoluble Part 3 of 4 $\mathrm{Ni}(\mathrm{OH})_{3}$ soluble insoluble Part 4 of 4 $\mathrm{Bi}\left(\mathrm{NO}_{3}\right)_{3}$ soluble insoluble

Solution

Solution Steps

Step 1: Determine the Solubility of PbBr$_2$

Lead(II) bromide, $\mathrm{PbBr}_{2}$, is generally considered insoluble in water. According to solubility rules, most bromides are soluble except those of lead(II), silver, and mercury(I).

Step 2: Determine the Solubility of Ni(OH)$_3$

Nickel(III) hydroxide, $\mathrm{Ni}(\mathrm{OH})_{3}$, is generally considered insoluble in water. Hydroxides are typically insoluble except for those of alkali metals and some alkaline earth metals.

Step 3: Determine the Solubility of Bi(NO$_3$)$_3$

Bismuth nitrate, $\mathrm{Bi}\left(\mathrm{NO}_{3}\right)_{3}$, is generally considered soluble in water. Nitrates are almost universally soluble.

Final Answer

\[ \boxed{\text{PbBr}_2 \text{ is insoluble}} \] \[ \boxed{\text{Ni(OH)}_3 \text{ is insoluble}} \] \[ \boxed{\text{Bi(NO}_3\text{)}_3 \text{ is soluble}} \]
