Explanation:

Formula to calculate pH of a chemical or solution is as follows.

pH = $-log [H^{+}]$

Therefore, calculate the pH of given chemicals as follows.

1). Oven cleaner

pH = $-log [H^{+}]$

= $-log [10^{-13}]$

= 13

2). Water

pH = $-log [H^{+}]$

= $-log [7 \times 10^{-7}]$

= 6.15

3). Blood

pH = $-log [H^{+}]$

= $-log [4 \times 10^{-8}]$

= 7.40

4). Vinegar

pH = $-log [H^{+}]$

= $-log [63 \times 10^{-4}]$

= 2.20
