Answer:

Ca²⁺, S⁻²

Explanation:

Calcium (Ca) is a <u>metallic</u> element and belongs to <u>group II</u> of the Periodic Table. So, it can lose 2 electrons to form the positively charged ion Ca²⁺.

Sulfur (S) is a <u>non-metal</u> element, so it has the tendency to gain electrons and to form anions. It accepts two electrons to form the sulfide ion S²⁻.

Write the Henderson-Hasselbalch equation for a solution of formic acid. Calculate the quotient [HCO2]/[HCO2H] at (a) pH 3.000; (
Elena L [17]

Answer:

a. 0.182

b. 1.009

c. 1.819

Explanation:

Henderson-Hasselbach equation is:

pH = pKa + log [salt / acid]

Let's replace the formula by the given values.

a. 3 = 3.74 + log [salt / acid]

3 - 3.74 = log [salt / acid]

-0.74 = log [salt / acid]

10⁻⁰'⁷⁴ = 0.182

b. 3.744 = 3.74 + log [salt / acid]

3.744 - 3.74 = log [salt / acid]

0.004 = log [salt / acid]

10⁰'⁰⁰⁴ = 1.009

c. 4 = 3.74 + log [salt / acid]

4 - 3.74 = log [salt / acid]

0.26 = log [salt / acid]

10⁰'²⁶ = 1.819
