16. if you measure the number of hydroxide ions to be 3.0x10⁻² moles, will the solution be acidic, basic, or neutral? explain your answer.
Answer
Brief Explanations:
In an aqueous solution, if the concentration of hydroxide - ions ($[OH^-]$) is greater than the concentration of hydrogen - ions ($[H^+]$), the solution is basic. At $25^{\circ}C$, in a neutral solution $[H^+]=[OH^-]=1.0\times 10^{-7}\ mol/L$. Given $[OH^-]=3.0\times 10^{-2}\ mol/L$ which is much larger than $1.0\times 10^{-7}\ mol/L$. So the solution is basic.
Answer:
The solution is basic.
