The approximate molar concentration of several chemicals are given. Find the pH of each use the calculator and round to the near
mojhsa [17]

Answer:

pH = 13 --- Oven Cleaner

pH = 6.2 --- Water

pH =7.4 --- Blood

pH = 2.2 --- Vinegar

Step-by-step explanation:

The given molar concentration are:[Missing from the question]

Oven Cleaner: [h+] = 10^{-13}

Water: [h+] = 0.0000007

Blood: [h+] = 0.00000004

Vinegar: [h+] = 0.0063

Required

Determine the pH

pH is calculated using:

pH = -\log(h+)

So, we have:

Oven Cleaner:

pH = -\log(10^{-13})

Using a calculator, we have:

pH = 13

Water:

pH = -\log(0.0000007)

Using a calculator, we have:

pH = -1*-6.2

pH = 6.2

Blood:

pH = -\log(0.00000004)

Using a calculator, we have:

pH = -1 * -7.4

pH =7.4

Vinegar:

pH = -\log(0.0063 )

Using a calculator, we have:

pH = -1 * -2.2

pH = 2.2
