Question
Tremolite is a double-chain silicate in the amphibole class. Use charge balancing to determine how many hydroxide ions are in the formula for tremolite, $\mathrm{Ca}_{2} \mathrm{Mg}_{5} \mathrm{Si}_{8} \mathrm{O}_{22}(\mathrm{OH})_{x}$
Step 1
The charges are as follows: - Calcium (Ca): +2 - Magnesium (Mg): +2 - Silicon (Si): +4 - Oxygen (O): -2 - Hydroxide (OH): -1 Now, we can calculate the total charge of the formula without the hydroxide ions: (2 Ca * +2) + (5 Mg * +2) + (8 Si * +4) + (22 O * -2) = Show more…
