Determine the ratio of cations to anions for the following ionic compounds
a. potassium, a salt substance
b. calcium floride, used in steel industry
c. aluminum oxide, known as corundum in the crystalline form
d. calcium oxide, used to remove sulfur dioxide from power plant exhaust
e. strontium chloride, used in fireworks
can i please get the answers
A.1:1
B.1:2
C.2:3
D.1:1
E.1:2
Hope this helps if you didn't understand the other person
a. The ratio of cations to anions for potassium, a salt substance, is 1:1. Just like a balanced relationship, they go hand in hand.
b. For calcium fluoride, used in the steel industry, the ratio of cations to anions is also 1:2. It seems like calcium believes in supporting its fluorine friend in a ratio that's twice as strong.
c. Aluminum oxide, known as corundum in crystalline form, has a ratio of cations to anions of 2:3. Apparently, aluminum believes in being generous and giving more love to oxygen.
d. Calcium oxide, used to remove sulfur dioxide from power plant exhaust, has a ratio of cations to anions of 1:1. Calcium believes in taking one for the team and standing strong right beside oxygen.
e. Strontium chloride, used in fireworks, has a ratio of cations to anions of 1:2. Strontium knows that if it wants to make a big sparkling impression in the sky, it needs to bring along twice as many chloride friends.
To determine the ratio of cations to anions for any ionic compound, we need to identify the charges of the cations and anions.
a. Potassium is a Group 1 element, so it has a charge of +1 when it forms an ion. Since it is listed alone as "potassium", we assume it is the cation. Therefore, the ratio of cations to anions is 1:0.
b. Calcium fluoride (CaF2) consists of a calcium ion (Ca2+) and two fluoride ions (F-). Calcium has a charge of +2, while fluorine has a charge of -1. The ratio of cations to anions is 1:2.
c. Aluminum oxide (Al2O3) consists of two aluminum ions (Al3+) and three oxygen ions (O2-). The ratio of cations to anions is 2:3.
d. Calcium oxide (CaO) consists of a calcium ion (Ca2+) and an oxygen ion (O2-). The ratio of cations to anions is 1:1.
e. Strontium chloride (SrCl2) consists of a strontium ion (Sr2+) and two chloride ions (Cl-). The ratio of cations to anions is 1:2.
Formulas are here. You can get the ratio from that.
a. K--there is neither cation nor anion here. I suspect you did write all of the material.
b. CaF2. Not the correct spelling of fluoride.
c. Al2O3
d. CaO
e. SrCl2
