pH value reference

• Water: pH is 6.5-7

• Saliva: pH value is 6.6~7.5

• Urine: The pH value is about 6.0. Depending on the food, the pH range is 4.5~8.0.

• Human blood: pH is 7.34-7.45

• Vinegar: pH value is 2.8~3.8

• Soy sauce: pH value is 4.5~4.8

• Aqueous solution of baking soda: NaHCO-solution. The solution is alkaline, with a pH of 7.5~8.5.

Between (because HCO; is weakly alkaline)

• Tea water: short-term brewing - the pH is about 5.5-6.5

• Coke soda: the pH value is about 2.2

• Stomach acid: between 1-2

• Distilled water: The pH of the distilled water that has just been distilled is 7, which is neutral. It's open and clean.

After a few days in the container, the pH of the distilled water will decrease, because the acidic carbon dioxide gas in the air dissolves in water, which reduces the pH value of the water.

• Vagina: The pH value is 4-5, which is the best pH state for women in this state.

The pH value will protect your body from some germs. Baking soda is bicarbonate.

Sodium (NaHCO.) is weakly alkaline after being dissolved in water, that is, the PH value is greater than 7.
