Chapter 4.7, Problem 1RC

Interpretation Introduction

Interpretation:

It should be determine that the final solution prepared after mixing a $25mL$ of $0.40MHCl$ and $32mL$ of $0.30MNaOH$ is acidic, basic or neutral

Concept introduction:

• $pH$ of a solution is the negative of the base $\text{-10}$ logarithm of the hydronium ion concentration.

  $\text{pH}\text{=}\text{-log}\left[{\text{H}}_{\text{3}}{\text{O}}^{\text{+}}\right]$

• For an acidic solution $\text{pH}\text{<7}$ and for a basic solution $\text{pH>}\text{7}$
• $\text{Concentration}=\frac{\text{Amount}\text{of}\text{the}\text{substance}}{\text{Volume}}$
• $\text{Amount}\text{of}\text{the}\text{substance}=\text{Concentration}\times \text{Volume}$
