How does the common-ion effect influence the Ph?
The common-ion effect decreases the solubility of a slightly soluble salt in a solution that already contains one of the ions of the salt. This leads to a decrease in the pH of the solution due to the shift in the equilibrium of the dissociation reaction towards the production of more undissociated molecules and fewer ions.
What is the pH of a lemon after digestion?
The pH of a lemon is typically around 2 to 3 before digestion due to its citric acid content. However, after digestion, the acidic components are metabolized, and the resulting pH of the urine can vary, often becoming more neutral or even slightly alkaline. The body regulates pH levels, so the final pH after digestion is influenced by various factors, including diet and metabolism. Overall, the lemon's acidity does not significantly affect the body's systemic pH.
What happens to the pH of water as a gaseous HCl is added?
When you blow out, you exhale carbon dioxide gas, which is soluble in water. The dissolved CO2 (known as carbonic acid) is acidic, and therefore the pH will fall, but not significantly. You will never be able to measurably determine that there is a difference....at least not with pH testing strips. However, if you put a very small amount (just a few grains) of sodium carbonate in about 100 mL of water and add a drop of phenolthalein, the solution will turn pink, indicating that it is a base (a very weak one, about pH 8) Then, if you blow bubbles into the water with a straw for about 2 minutes, the solution will go from pink to clear, indicating that it is no longer a base. Your breath has neutralized the base.
What is the pH value in plants?

5.5 - 6.5
the decrease of the pH in sauerkraut is due to the succession of lactic and acetic acid microorganisms that grow on the brine solution making it acidic.
Why does PH eagle PH tamarawand PH freshwater crocodile are endangered?
One reason that Philippine Tarsiers are endangered is that their homes and habitat are being destroyed. The trees are being cut down and the land is being cleared for crop land. Secondly, poachers and hunters capture and kill them. They are captured to be sold as pets. Problem is they don't do as well living around humans and they usually live only half as long as they would in the wild. Also, some of the tarsiers have been so traumatized by captivity that they have committed suicide by beating their heads against the cages, or drowning themselves in their drinking bowls.
What is the pH levels of barium nitrate?
Barium is the cation of Ba(OH)2, a strong base which fully ionizes. Chloride is the anion of HCl, a strong acid which fully ionizes. BaCl2 is neutral at any concentration. Ba has no acidic properties or Ba(OH)2 wouldnt fully ionize and the same goes for Cl-
What effect the pH have on protein digestion with pepsin?
It is most effective at around pH 2, and becomes inactive over 5.
How calculate pH for a solution?
HCl is a strong acid and dissociates completely. Therefore it can be found using the equation:
ph= -log [H+]
Why is cellular pH kept near a value of 7?
Cellular pH is kept near a value of 7 because it is the optimal pH for most enzymes to function properly. Fluctuations in pH can disrupt enzyme activity and lead to cellular dysfunction or damage. Maintaining a stable pH also helps regulate important cellular processes and maintain homeostasis.
What dos the pH scale actually measure?
To answer this question we would need to know the type of drain cleaner you are referring to. If you are talking about liquid drain cleaner it has a pH of 14. But the pH ranges from 13 to 14 depending on the type.
Pepsin doesn't affect the pH but it is active in an acidic environment.
What is laxative on the pH scale?
The pH of a laxative, is up the but and around the corner. Just playing its 3 degrees.
