Tests show that the hydrogen ion concentration of a sample of apple juice is 0.0003 and that of ammonia is [tex]$1.3 \times 10^{-9}$[/tex]. Find the approximate pH of each liquid using the formula [tex]$pH = -\log \left[ H ^{+}\right]$[/tex], where [tex]\left[ H ^{+}\right][/tex] is the hydrogen ion concentration.

The pH value of the apple juice is [tex]$\square$[/tex].

The pH value of ammonia is [tex]$\square$[/tex].


Sagot :

To find the pH value of each liquid using the given formula [tex]\( pH = -\log[H^+] \)[/tex], let's follow these steps:

1. Identify the hydrogen ion concentrations:
- For apple juice: [tex]\( [H^+] = 0.0003 \)[/tex]
- For ammonia: [tex]\( [H^+] = 1.3 \times 10^{-9} \)[/tex]

2. Calculate the pH of apple juice:
- Using the formula [tex]\( pH = -\log[H^+] \)[/tex], we substitute the concentration of hydrogen ions in apple juice.
- [tex]\( pH_{apple\_juice} = -\log(0.0003) \)[/tex]
- The pH value of apple juice is approximately [tex]\( 3.52 \)[/tex].

3. Calculate the pH of ammonia:
- Similarly, for ammonia, we use the hydrogen ion concentration.
- [tex]\( pH_{ammonia} = -\log(1.3 \times 10^{-9}) \)[/tex]
- The pH value of ammonia is approximately [tex]\( 8.89 \)[/tex].

Therefore:

- The pH value of the apple juice is 3.52.
- The pH value of ammonia is 8.89.
