Figure 1-52. Partial neutralization of H2SO4 with NaOH.
Similarly, if there is not enough acid to neutralize all of the OH groups on a metal hydroxide, a hydroxo salt
is formed. The beautiful green mineral malachite mentioned above is a naturally occurring hydroxo salt, Cu2
. 1.13.3. Exercises.
1. Balance the following chemical equations for neutralization reactions between an acid and a base.
+ HCl = MgCl2
(b) KOH + H3
↓ + H2
2. How much HBr is needed to neutralize 60 g of NaOH? Answer
3. 50 g of a 7% solution of HCl was mixed with 30 g of a 9% solution of KOH. A piece of blue litmus paper was then dipped in the resultant solution. Did the litmus paper color change to red? Answer
