Question

Write a balanced equation for the neutralization of each of the following:

a.${\mathrm{H}}_2{\mathrm{SO}}_4\left(aq\right)\text{and}\mathrm{NaOH}\left(aq\right)$

b.$\mathrm{HCl}\left(aq\right)\text{and}\mathrm{Fe}\left(\mathrm{OH}{)}_3\right(s)$

c.${\mathrm{H}}_2{\mathrm{CO}}_3\left(aq\right)and\mathrm{Mg}\left(\mathrm{OH}{)}_2\right(s)$

Short answer

a.${\mathrm{H}}_2{\mathrm{SO}}_4\left(aq\right)+2\mathrm{NaOH}\left(aq\right)\to 2{\mathrm{H}}_2\mathrm{O}\left(l\right)+{\mathrm{Na}}_2{\mathrm{SO}}_4\left(aq\right)$

b.$3\mathrm{HCl}\left(aq\right)+\mathrm{Fe}\left(\mathrm{OH}{)}_3\right(s)\to 3{\mathrm{H}}_2\mathrm{O}(l)+{\mathrm{FeCl}}_3(aq)$

c.${\mathrm{H}}_2{\mathrm{CO}}_3\left(aq\right)+\mathrm{Mg}\left(\mathrm{OH}{)}_2\right(s)\to 2{\mathrm{H}}_2\mathrm{O}(l)+{\mathrm{MgCO}}_3(aq)$

Step-by-step solution

Part (a) Step 1: Given Information

Write a balanced equation for the neutralization of-

${\mathrm{H}}_2{\mathrm{SO}}_4\left(aq\right)\text{and}\mathrm{NaOH}\left(aq\right)$

Part (a) Step 2: Explanation

The balanced equation for the neutralization of ${\mathrm{H}}_2{\mathrm{SO}}_4\left(aq\right)\text{and}\mathrm{NaOH}\left(aq\right)$is,

${\mathrm{H}}_2{\mathrm{SO}}_4\left(aq\right)+2\mathrm{NaOH}\left(aq\right)\to 2{\mathrm{H}}_2\mathrm{O}\left(l\right)+{\mathrm{Na}}_2{\mathrm{SO}}_4\left(aq\right)$

The reaction of $H_{2}S{O}_4$with NaOH gives water $H_{2}O$and sodium sulfate salt $N{a}_{2}S{O}_4$.

Part (b) Step 1: Given Information

Write a balanced equation for the neutralization of-

$\mathrm{HCl}\left(aq\right)\text{and}\mathrm{Fe}\left(\mathrm{OH}{)}_3\right(s)$

Part (b) Step 2: Explanation

The balanced equation for the neutralization of $\mathrm{HCl}\left(aq\right)\text{and}\mathrm{Fe}\left(\mathrm{OH}{)}_3\right(s)$is,

$3\mathrm{HCl}\left(aq\right)+\mathrm{Fe}\left(\mathrm{OH}{)}_3\right(s)\to 3{\mathrm{H}}_2\mathrm{O}(l)+{\mathrm{FeCl}}_3(aq)$

The reaction of HCL with$Fe{\left(OH\right)}_3$gives water$H_{2}O$and ferric chloride salt$FeC{l}_3$.

Part (c) Step 1: Given Information

Write a balanced equation for the neutralization of-

${\mathrm{H}}_2{\mathrm{CO}}_3\left(aq\right)\text{and}\mathrm{Mg}\left(\mathrm{OH}{)}_2\right(s)$

Part (c) Step 2: Explanation

The balanced equation for the neutralization of ${\mathrm{H}}_2{\mathrm{CO}}_3\left(aq\right)\text{and}\mathrm{Mg}\left(\mathrm{OH}{)}_2\right(s)$is,

${\mathrm{H}}_2{\mathrm{CO}}_3\left(aq\right)+\mathrm{Mg}\left(\mathrm{OH}{)}_2\right(s)\to {\mathrm{H}}_2\mathrm{O}(l)+{\mathrm{MgCO}}_3(aq)$

The reaction of $H_{2}C{O}_3$with $Mg{\left(OH\right)}_2$gives water $H_{2}O$and magnesium carbonate salt$MgC{O}_3$
