The pH of media decreases after irradiation due to the production of reactive species such as free radicals, ions, and acids as a result of radiation-induced chemical reactions. These reactive species can lead to the formation of acidic compounds, which subsequently lowers the pH. Additionally, the breakdown of organic molecules and the release of protons during these processes further contribute to the acidity of the media. Overall, the changes in chemical composition and the increase in acidic byproducts are responsible for the observed decrease in pH.
What else can I help you with?
What will neutralise pH 13.5?
Adding an acid the pH decrease.
Is the keeping quality of the unsterilized media affect pH?
Yes, the keeping quality of unsterilized media can affect pH due to microbial growth and metabolism. As microbes grow, they can produce acids or bases that alter the pH of the media. Monitoring the pH regularly and using sterile techniques to minimize contamination can help maintain the desired pH of the media.
How does heat effect pH level?
Heating pure water the pH decrease.
Will NH3 increase decrease or no change in the pH when added to water?
The pH deccrease.
What is the effect of HCl on the pH if water?
Adding hydrogen chloride to water the pH decrease.
When citric acid is added will the pH increase or decrease?
When citric acid is added, or any acid for that matter, the pH of a substance will decrease. This is because since acids have a low pH they will decrease the pH of other substances when added to it.
What will neutralise pH 13.5?
Adding an acid the pH decrease.
What will happen to the pH of Na OH when mixed with acid?
Generally, the pH will decrease, depending on the strength of the acid. The stronger the acid is, the more the pH will decrease, when mixed with NaOH.
Does the increase or decrease of CO2 affect the pH level?
Yes, the increase of CO2 can decrease the pH level of a solution, leading to acidification.
Is the keeping quality of the unsterilized media affect pH?
Yes, the keeping quality of unsterilized media can affect pH due to microbial growth and metabolism. As microbes grow, they can produce acids or bases that alter the pH of the media. Monitoring the pH regularly and using sterile techniques to minimize contamination can help maintain the desired pH of the media.
How does heat effect pH level?
Heating pure water the pH decrease.
Why will a decrease in pH of the stomach affect protein digestion?
Decrease in pH of the stomach will distort the active site of the enzyme pepsin, which affects its action.
Will H2C2O4 increase decrease or no change in the pH when added to water?
H2C2O4, also known as oxalic acid, will decrease the pH when added to water. This is because oxalic acid is a weak acid that will dissociate in water to release hydrogen ions, leading to an increase in H+ concentration and a decrease in pH.
Does the pH of the media change during sterilization why?
The pH is dependent on the temperature.
If an acid is added to water the PH will?
decrease.
Will NH3 increase decrease or no change in the pH when added to water?
The pH deccrease.
What is the effect of HCl on the pH if water?
Adding hydrogen chloride to water the pH decrease.
