Following are the pH of the mentioned things:

Explanation:

pH is the measure of the acidity or the basicity of any substance or any chemical. It consists of a scale displaying the numbers from 0 to 14, where 7 is neutral.

Moving on to the left side of 7, acidity increases, whereas moving on to the right side of 7, the basicity increases.

• pH of NaOH: 13 (strong base)
• pH of pure water: 7 (neutral)
• pH of blood: 7.4 (slightly basic)
• pH of gastric juice: 1.5 to 3.5 (strong acid)
• pH of animals: 8 (slightly basic)
• pH of pure soil: 6.5 (slightly acidic)
• pH of tooth decay cause: 5 to 5.5 (acidic)
