The hepatic Bile has a pH of about 7.4 and the Bladder bile has a pH of about 6.8.
On an average the pH of bile juice is between 6.8 and 7.6.
Adding water does not always decrease pH. pH is a measure of the concentration of hydrogen ions, also called hydronium ions. They are inversely related. More hydrogen ions means a lower pH.
A base has a pH greater than 7 (neutral) because it has an increased amount of hydroxide ions which causes a lower amount of hydrogen ions. Adding more water to a base solution causes the concentration of the hydroxide ions to become less, thus due to equilibrium, causing the hydrogen ion concentration to increase. This does cause pH to become less ... decrease.
But an acid solution does the exact opposite when water is added. It already has a large concentration of hydrogen ions, but as water is added the concentration decreases and this causes pH to increase.
What is pH of potassium sulfate granular?
Granular potassium sulfate does not have a pH. A pH value can only be given to a solution.
What happens to the hydrogen ion when the PH increases?
the pH level decreases or becomes more acidic
How does neutralization change the pH numbers of an acid?
When anything is neutralized, the pH value moves closer to 7. In addition, when a weak acid is being neutralized, a buffer is also being formed, until all the weak acid has been converted to the salt.
How do you determine the pH of each solution?
acidic, neutral, or basic. Salts that form from a strong acid and a weak base are acid salts, like ammonium chloride
What is the pH number of a dilute solution of a weak base?
The pH of a weak base can be anything greater than 7.0. Generally, weak bases do have a lower pH that strong bases, but this is not always true. The fact that a base is weak only means that it does not completely ionize in solution. The pH of a weak base depends only upon the concentration of hydroxide ions (OH-) in solution.
What is the pH for orange juice?
The pH of Orange Juice is 3, meaning it's very acidic. The concentration of Hydrogen ions is 10-3 m/L.

very acidic . neutral ... very basic
The Ph scale is from 0-14. 7 is neutral. So, 9 would be increasing to alkaline. below 7 is acidic. Red litmus paper would turn blue in soapy water, and blue litmus paper would stay blue. Soapy water is a base.
pH is a measure of the acidity/or alkalinity of a substance. Substances that are more acidic have a lower pH value. It may help you to remember if you think of the pH scale as a measure of alkalinity (the opposite of acidity), that way, as the numbers get bigger the alkalinity increases. Acidity is due to the presence of hydrogen ions within the substance, and a greater concentration of hydrogen ions will cause something to be more acidic.
pH is commonly measured by introducing the substance to a pH strip, and comparing the color the strip turns against a scale provided with the strip. A pH strip is a piece of paper in which is embedded some substance that reacts to a certain level of acidity by changing color. Litmus is perhaps the most famous pH indicator (thus the expression of applying a litmus test) and will turn red at a pH below 4.5 and blue above 8.3. There are a number of other substances that change color at a specific acidity. A very accurate pH test strip works by embedding some of these substances in the strip so that different substances will change color, thus reveling the acidity of the substance.
What Is the pH of kitchen and bathroom cleaner?
come on people i need to know i am really stuck wiv ma omework
What specific substance could i add to my soil if the pH is too acidic?
an alkali
My answer will be a little more detailed than the previous. First you need know what acid you are dealing with. A response to the question who do you raise the PH of Nitric Acid? The response was you add water, which is somewhat correct but barely. We use two different chemicals to adjust PH in acids. Lets say we have a batch of Nitric Acid at 3ph and we need to get it to 7. Very carefully if you are doing this manually you will need to add Sodium Hydroxide AKA caustic soda. In the industry this is the go to chemical to raise the PH. BE CAREFUL caustic hurts like a you know what if you get it on you, I once got it in my eye. Not fun!. When adding the caustic do it slowly and mix the acids like you would a sauce. Add small drops of it. Adding a lot within seconds will bring the PH to 11. Thats called overshooting. If you overshoot. Follow the same procedure as I mentioned but switch the caustic with hydrocloric acid. Caustic raised the PH, Hydro lowers it.

What is the best range for the pH of soil?
the best pH for plants in order to grow is 5-7 this means that having slightly acidic soil to neutral soils is the best for growing plants. Plants will still grow in slightly basic soil but not as well
Is the pH of an acid higher or lower than water?
Water at different temperatures has different densities. Water at 4°C, is the densest and so it is heavier by volume than water at lower or higher temperatures. However, when water is mixed, the temperature will become the average of the two water temperatures. This means that you can't see one floating on the other - even if you coloured one of the water temperatures, it would mix almost immediately.
Something else to consider is that water is not as homogenous as most people think. Naturally occuring water contains deuterium oxide, 17O and 18O isotope water, and tritiated water are forms of heavy water.
