Whether the pH of a solution can be negative should be explained. Concept Introduction: To express the small number, p scale is used, which implies to take the log of a number. Since, the concentration of [H + ] in aqueous solution is small, by using the p scale in the form of pH scale, it is better way to represent acidity of solution. Thus, pH = -log [H + ] .

Interpretation Introduction

Interpretation:

Whether the pH of a solution can be negative should be explained.

Concept Introduction:

To express the small number, p scale is used, which implies to take the log of a number. Since, the concentration of [H+] in aqueous solution is small, by using the p scale in the form of pH scale, it is better way to represent acidity of solution.

Thus, pH = -log [H+].

Predict the major products of this organic reaction: HBr (1 equiv) cold ? Some important notes: • Draw the major product, or products, of this reaction in the drawing area below. • You can draw the products in any arrangement you like. • Pay careful attention to the reaction conditions, and only include the major products. • Be sure to use wedge and dash bonds when necessary, for example to distinguish between major products that are enantiomers. • Note that there is only 1 equivalent of HBr reactant, so you need not consider the case of multiple additions.
