What else can I help you with?
Will NH3 increase decrease or no change in the pH when added to water?
The pH deccrease.
What effect may bacterial contamination have on urine pH?
Bacterial contamination will cause no effects if the sample is tested directly after collection. However, if the sample is allowed to sit, bacteria will multiply and raise the urine pH. Urine pH above 8 is abnormal.
What pH lipases is more active?
Lipases typically exhibit optimal activity at a pH range of around 7 to 9, which corresponds to neutral to slightly alkaline conditions. However, some specific lipases, such as those from certain bacteria or fungi, may have optimal activity at more extreme pH levels, either acidic or alkaline. The specific pH for maximum activity can vary depending on the source of the lipase and its intended application. Overall, lipases are generally more active near neutral pH.
Why does pH decrease when digesting triglycerides?
During the digestion of triglycerides, they are broken down into fatty acids and glycerol by enzymes such as lipases. The released fatty acids can lower the pH of the surrounding environment because they are weak acids. As these fatty acids accumulate, they contribute to a more acidic environment, resulting in a decrease in pH. This process is particularly evident in the stomach and small intestine, where lipid digestion occurs.
What is the increase in acidity associated with a decrease of one unit on the pH scale?
A decrease of one unit on the pH scale represents a tenfold increase in acidity. This is because the pH scale is logarithmic, meaning each whole number change reflects a tenfold change in hydrogen ion concentration. For example, a solution with a pH of 5 is ten times more acidic than one with a pH of 6.
What type of bacteria is most likely to go through fermentation?
Assume you are growing bacteria on a lipid medium that started at pH 7. The action of bacterial lipases should cause the pH of the medium to increase or decrease? Why?
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.
Does algae increase pH or decrease pH of water?
Algae draws all available CO2 out of water, causing its pH to increase.
Will NH3 increase decrease or no change in the pH when added to water?
The pH deccrease.
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 is the effects of an increase in PCO2?
Plasma pH will Decrease
When the kidneys increase the excretion of bicarbonate the pH will?
ph will become elevated and blood will be more acidic
Will the pH increase or decrease if you mix two acids having different pH value?
In general the highest will decrease (more) and the lowest will increase (somewhat), but NEVER linearly average pH values, because it is an exponential unit. ( [H+] = 10-pH )
An increase in hydrogen atoms will do what to pH?
pH means power of hydrogen. So, an increase in no. of hydrogen will increase the pH.
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 bicarbonate increase or decrease pH levels in a solution?
Bicarbonate increases pH levels in a solution.
Does an increase in carbon dioxide levels lead to a decrease in pH levels?
Yes, an increase in carbon dioxide levels leads to a decrease in pH levels, as carbon dioxide reacts with water to form carbonic acid, which lowers the pH of the solution.
