Question

ami day: formulas for acids name construct the chemical formula for each of the following acids. resources are on the las couple of pages. subscripts must be small #s written/typed to lower right! 1 dichromic acid 2. hydrochloric acid 3 hydrofluoric acid 4. chlorous acid 5 arsenic acid 6. hydrophosphoric acid 7 hydrocyanic acid 8. iodic acid 9 oxalic acid 10 hydrobromic acid 11 hydronitric acid 12. sulfuric acid 13. nitrous acid 14. phosphorous acid 15. tetraboric acid 16. hydrosulfuric acid

Explanation:

Step1: Recall acid naming rules

Binary acids use "hydro-", end in "-ic"; oxyacids use polyatomic ions.

Step2: Match name to ion/formula

1. Dichromic acid: Uses $\text{Cr}_2\text{O}_7^{2-}$, add $\text{H}^+$ to balance charge.

$2\text{H}^+ + \text{Cr}_2\text{O}_7^{2-}
ightarrow \text{H}_2\text{Cr}_2\text{O}_7$

1. Hydrochloric acid: Binary acid, $\text{Cl}^-$ + $\text{H}^+$.

$\text{H}^+ + \text{Cl}^-
ightarrow \text{HCl}$

1. Hydrofluoric acid: Binary acid, $\text{F}^-$ + $\text{H}^+$.

$\text{H}^+ + \text{F}^-
ightarrow \text{HF}$

1. Chlorous acid: Oxyacid, uses $\text{ClO}_2^-$.

$\text{H}^+ + \text{ClO}_2^-
ightarrow \text{HClO}_2$

1. Arsenic acid: Oxyacid, uses $\text{AsO}_4^{3-}$.

$3\text{H}^+ + \text{AsO}_4^{3-}
ightarrow \text{H}_3\text{AsO}_4$

1. Hydrophosphoric acid: Binary acid, $\text{P}^{3-}$ + $\text{H}^+$.

$3\text{H}^+ + \text{P}^{3-}
ightarrow \text{H}_3\text{P}$

1. Hydrocyanic acid: Binary acid, $\text{CN}^-$ + $\text{H}^+$.

$\text{H}^+ + \text{CN}^-
ightarrow \text{HCN}$

1. Iodic acid: Oxyacid, uses $\text{IO}_3^-$.

$\text{H}^+ + \text{IO}_3^-
ightarrow \text{HIO}_3$

1. Oxalic acid: Oxyacid, uses $\text{C}_2\text{O}_4^{2-}$.

$2\text{H}^+ + \text{C}_2\text{O}_4^{2-}
ightarrow \text{H}_2\text{C}_2\text{O}_4$

1. Hydrobromic acid: Binary acid, $\text{Br}^-$ + $\text{H}^+$.

$\text{H}^+ + \text{Br}^-
ightarrow \text{HBr}$

1. Hydronitric acid: Binary acid, $\text{N}^{3-}$ + $\text{H}^+$.

$3\text{H}^+ + \text{N}^{3-}
ightarrow \text{H}_3\text{N}$

1. Sulfuric acid: Oxyacid, uses $\text{SO}_4^{2-}$.

$2\text{H}^+ + \text{SO}_4^{2-}
ightarrow \text{H}_2\text{SO}_4$

1. Nitrous acid: Oxyacid, uses $\text{NO}_2^-$.

$\text{H}^+ + \text{NO}_2^-
ightarrow \text{HNO}_2$

1. Phosphorous acid: Oxyacid, uses $\text{HPO}_3^{2-}$ (balanced for charge).

$2\text{H}^+ + \text{HPO}_3^{2-}
ightarrow \text{H}_3\text{PO}_3$

1. Tetraboric acid: Oxyacid, uses $\text{B}_4\text{O}_7^{2-}$.

$2\text{H}^+ + \text{B}_4\text{O}_7^{2-} + \text{H}_2\text{O}
ightarrow \text{H}_2\text{B}_4\text{O}_7$

1. Hydrosulfuric acid: Binary acid, $\text{S}^{2-}$ + $\text{H}^+$.

$2\text{H}^+ + \text{S}^{2-}
ightarrow \text{H}_2\text{S}$

Answer:

1. $\text{H}_2\text{Cr}_2\text{O}_7$
2. $\text{HCl}$
3. $\text{HF}$
4. $\text{HClO}_2$
5. $\text{H}_3\text{AsO}_4$
6. $\text{H}_3\text{P}$
7. $\text{HCN}$
8. $\text{HIO}_3$
9. $\text{H}_2\text{C}_2\text{O}_4$

11. $\text{H}_3\text{N}$
12. $\text{H}_2\text{SO}_4$
13. $\text{HNO}_2$
14. $\text{H}_3\text{PO}_3$
15. $\text{H}_2\text{B}_4\text{O}_7$
16. $\text{H}_2\text{S}$
