Chapter 2: Q96P (page 84)

Give the name and formula for the acid derived from each of the following anions

  1. hydrogen sulfate
  2. lO3-
  3. cyanide
  4. HS-

Short Answer

Expert verified
  1. The acid derivative of hydrogen sulfate isH2SO4 i.e., sulfuric acid.
  2. The acid derivative of lO3isHlO3.
  3. The acid derivative of cyanide isHCN.
  4. The acid derivative ofHS- isH2S.

Step by step solution

01

Acid derivative of hydrogen sulfate

Hydrogen sulfate has a formulaHSO4-It has a charge of -1 so add 1 hydrogen to remove the charge. The acid derivative of hydrogen sulfate H2SO4isi.e., sulfuric acid.

02

Acid derivative of IO3-

lO3-has a charge of -1, so adding one H+ ion charge will be nullified. Acid derivative of lO3-is HlO3.

03

Acid derivative of cyanide

The formula of cyanide isCN- It also has a charge of -1, so adding one H+ ion charge will be nullified. The acid derivative of cyanide is HCN.

04

Acid derivative of HS-

HS-has a charge of -1 so add 1 hydrogen to remove the charge. Acid derivative ofHS-isH2s.

State the mass law(s) demonstrated by the following experimental results, and explain your reasoning:

Experiment 1: A student heats 1.00 g of a blue compound and obtains 0.64 g of a white compound and 0.36 g of a colourless gas.

Experiment 2: A second student heats 3.25 g of the same blue compound and obtains 2.08 g of a white compound and 1.17 g of a colourless gas.

Correct the formula to match the name of the following compounds:

  1. Iron(III) oxide,;Fe3O4
  2. Chloric acid,;HCl
