Chapter 2, Problem 1P
Summary Introduction

To examine: Whether the statement, “A 10-8 M solution of HCl has a pH of 8”, is true or false.

Introduction: The potential of hydrogen (pH) is the negative logarithm of the concentration of hydrogen (H+ ) ions. It determines acidity and alkalinity of a substance. Acids have pH lower than 7, whereas alkalis have pH more than 7. The solutions that are not considered under acid or alkali are called neutral solutions and have a pH equal to 7.

Expert Solution & Answer

Answer to Problem 1P

Correct answer: The statement is false.

Explanation of Solution

The pH of hydrochloric acid (HCL) cannot be equal to 8 because HCL is a strong acid, and the pH of an acidic solution can never be higher than 7.

Hence, the statement is false.

In humans, red-green color blindness is recessive and X-linked, whereas albinism is recessive and autosomal.  What types of children can be produced as the result of marriage between two homozygous parents, a normal-vision albino woman and a color-blind, normal male?
In Drosophila, an X linked recessive mutation, scalloped (sd), causes irregular wing margins.  Diagram the F1 and F2 results if a (a) scalloped female is crossed with a normal male; (b) a scalloped male is crossed with a normal female (assume the female is homozygous).  Compare these results to what you would find if the trait was not sex linked.
