To find :
a.
Answer to Problem 42IP
The hydrogen ion concentration of coffee is
Explanation of Solution
Given information :
The PH scale range from 0 to 14, with a PH 7 being neutral. As the PH decrease the substance is more acidic.
Calculation :
The greatest hydrogen ion concentration in the table is coffee because its exponent
Hence,the hydrogen ion concentration of coffee is
b.
To find : which substance has a hydrogen ion concentration of one millionth
b.
Answer to Problem 42IP
The substance would be milk.
Explanation of Solution
Given information :
The table shows the average lengths of different objects
Calculation :
Therefore the substance that has a hydrogen ion concentrated of one millionth is
c.
To find : how many times as great is the hydrogen ion concentration of coffee as the hydrogen ion concentration of pure water
c.
Answer to Problem 42IP
The hydrogen ion concentration of coffee is
Explanation of Solution
Given information :
The PH scale range from 0 to 14, with a PH 7 being neutral. As the PH decrease the substance is more acidic.
Calculation :
Therefore, the hydrogen ion of coffee is greater than pure water bye
Hence, the hydrogen ion concentration of coffee is
