Question

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

a. ${\mathrm{H}}_3{\mathrm{PO}}_4\left(aq\right)and\mathrm{NaOH}\left(aq\right)$

b.$\mathrm{HI}\left(aq\right)and\mathrm{LiOH}\left(aq\right)$

c.${\mathrm{HNO}}_3\left(aq\right)and\mathrm{Ca}\left(\mathrm{OH}{)}_2\right(s)$

Short answer

a.${\mathrm{H}}_3{\mathrm{PO}}_4\left(aq\right)+3\mathrm{NaOH}\left(aq\right)\to 3{\mathrm{H}}_2\mathrm{O}\left(l\right)+{\mathrm{Na}}_3{\mathrm{PO}}_4\left(aq\right)$

b.data-custom-editor="chemistry" $\mathrm{HI}\left(aq\right)+\mathrm{LiOH}\left(aq\right)\to {\mathrm{H}}_2\mathrm{O}\left(l\right)+\mathrm{LiI}\left(aq\right)$

c.$2{\mathrm{HNO}}_3\left(aq\right)+\mathrm{Ca}\left(\mathrm{OH}{)}_2\right(s)\to 2{\mathrm{H}}_2\mathrm{O}(l)+\mathrm{Ca}{\left({\mathrm{NO}}_3\right)}_2(aq)$

Step-by-step solution

Part (a) Step 1: Given Information 

Write a balanced equation for the neutralization of-

${\mathrm{H}}_3{\mathrm{PO}}_4\left(aq\right)\text{and}\mathrm{NaOH}\left(aq\right)$

Part (a) Step 2: Explanation 

The balanced equation for the neutralization of ${\mathrm{H}}_3{\mathrm{PO}}_4\left(aq\right)\text{and}\mathrm{NaOH}\left(aq\right)$is,

${\mathrm{H}}_3{\mathrm{PO}}_4\left(aq\right)+3\mathrm{NaOH}\left(aq\right)\to 3{\mathrm{H}}_2\mathrm{O}\left(l\right)+{\mathrm{Na}}_3{\mathrm{PO}}_4\left(aq\right)$

The reaction between $H_{3}P{O}_4$and $NaOH$gives water and trisodium phosphate.

Part (b) Step 1: Given Information 

Write a balanced equation for the neutralization of-

$\mathrm{HI}\left(aq\right)\text{and}\mathrm{LiOH}\left(aq\right)$

Part (b) Step 2: Explanation 

The balanced equation for the neutralization of $\mathrm{HI}\left(aq\right)\text{and}\mathrm{LiOH}\left(aq\right)$is,

$\mathrm{HI}\left(aq\right)+\mathrm{LiOH}\left(aq\right)\to {\mathrm{H}}_2\mathrm{O}\left(l\right)+\mathrm{LiI}\left(aq\right)$

The reaction between HI and LiOH gives water and lithium iodide.

Part (c) Step 1: Given Information 

Write a balanced equation for the neutralization of-

${\mathrm{HNO}}_3\left(aq\right)\text{and}\mathrm{Ca}\left(\mathrm{OH}{)}_2\right(s)$

Part (c) Step 2: Explanation 

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

${\mathrm{HNO}}_3\left(aq\right)+\mathrm{Ca}\left(\mathrm{OH}{)}_2\right(s)\to {\mathrm{H}}_2\mathrm{O}(l)+\mathrm{Ca}{\left({\mathrm{NO}}_3\right)}_2(aq)$

The reaction between $HN{O}_3$and $Ca{\left(OH\right)}_2$ gives water and calcium nitrate salt.
