Interpretation Introduction

Interpretation:

For which of the given weak acid solution can we most likely neglect x in the denominator of the equilibrium expression in the determination of pH has to be identified

Concept Information:

Weak acid:

Weak acids ionize only to limited extent in water. At equilibrium, an aqueous solution of a weak acid has a mixture of unionized acid molecules, hhydronium ions and corresponding conjugate base.

pH definition:

The concentration of hydrogen ion is measured using pH scale. The acidity of aqueous solution is expressed by pH scale.

The pH of a solution is defined as the negative base-10 logarithm of the hydrogen or hydronium ion concentration.

pH = -log[H3O+]

Draw the major substitution products you would expect for the reaction shown below. If substitution would not occur at a significant rate under these conditions, check the box underneath the drawing area instead. Be sure you use wedge and dash bonds where necessary, for example to distinguish between major products. Note for advanced students: you can assume that the reaction mixture is heated mildly, somewhat above room temperature, but strong heat or reflux is not used. Cl Substitution will not occur at a significant rate. Explanation Check :☐ O-CH + Х Click and drag to start drawing a structure.
