tears are 5.0 blood is 7.4 but the both can kill bacteria. with the acid in them.
We need to see what reaction that you are referring is.
Saliva is more acidic than tears. Saliva typically has a pH range of 6.0 to 7.4, while tears have a slightly higher pH range of 7.0 to 7.8.
Tears are slightly acidic, with a pH of around 7.4. This pH helps to protect the eyes from harmful microbes and maintain the health of the cornea.
Blood pH = 7.40 (+/- 0.05) (THIS IS THE ANSWER TO THE PH OF BLOOD IS NEAREST TO WHAT NUMBER)=#7
The pH of tears typically ranges from 7.0 to 7.4, making them slightly alkaline. This helps to maintain eye health and protect the eyes from infections or irritations.
saliva can have a pH from 6.0 to a 7.4 .
The pH is higher.
Normal Ph value of Blood 7.35 to 7.40.
acid pH < 7base pH > 7
arterial blood pH = 7.41 and venous blood pH = 7.36. Because the normal pH of arterial blood is 7.41 a person is considered to have acidosis when the pH of blood falls below this value and to have alkalosis when the pH rises above 7.41. hope i helped :D
Your gastric fluid is a 1 on the pH scale, being extremely acidic, blood and tears are about a 7 .
arterial blood pH = 7.41 (outgoing from heart) venous blood pH = 7.36 (returning to heart)
