For a solution to be tested in this experiment and must be buffered to pH of 10, the [OH-] change will be, The hydroxide concentration would be higher and the formation of insoluble hydroxide salts with Mg^2 and Ca^2 would cause the determined concentration of water hardness to be too low.
<h3>What would be the [OH-] change?</h3>
Generally, the equation for the Total hardness is mathematically given as
Where
D=0.02/0.01=2
Therefore
T=1632ppm
in conclusion, The hydroxide concentration would be higher .
