At a certain temperature the pH of a neutral solution is 7.56 What is the value of Kw at that temperature?

Kw = [H+][OH-]
[H+] = 10-pH = 10-7.56
In neutral pure water the concentration of H+ and OH- is equal.
[OH-] = 10-7.56
Kw = [H+][OH-] = 10-7.56 * 10-7.56 = 10-15.12

What is a pH of a Neutral solution like pure water?
A neutral solution has a pH value of exactly 7 (at 25oC).See the Related Questions to the for more information about acids, bases and the pH scale.Neutral is neither acid (< 7) nor base (> 7), hence the name neutralThe pH value of 7.0 is considered to be neutral. Pure water has a pH of 7.0Typically a pH of 7 is considered "neutral" since it is the pH of water.7Actually that's at 25 Degree CAt 37 degrees C (body temp) its 7.4
How does homeostasis impact the human body?
Maintain a normal value of certain body temperature.
What can change the set point for body temperature?
One of the most common causes for a temperature set point change is an acute infection with a virus or bacteria. Part of the immune response is to invoke a fever, which is actually a resetting of the core body temperature to a higher value. After a few days, the infection is generally cleared and the fever breaks, resetting the core body temperature to normal. Other causes include certain medications, some endocrine disorders and certain cancers.

Some factors that may influence enzyme activity?
A low temperature can slow down enzyme activity and high temperatures can denature an enzyme making it unusable. pH levels also affect enzyme activity. Every cell has an ideal temperature and pH
What is pH value of neutral solution?

What is acidic and basic pH?
At the temperature of 298 K, the pH 7.0 indicates neutral solution. Any value below is acidic and any value above is basic.
What is the pH value of table salt solution?
The table salt solution is neutral.
What is the pH value of salt solution?
Salt is neutral, and water is neutral so I think it must be neutral (pH 7).
What is a neutral solution?
A neutral solution can refer to many things, though I assume you mean in terms of pH. Neutral solutions have a pH of 7. Pure water has this pH value.
What is the pH neutral solution?
When a pH level is 7.0, it is defined as 'neutral' at 25°C because at this pH the concentration of H3O+ equals the concentration of OH− in pure water. - Wikipedia

Sodium chloride solution is neutral.
Term used to describe a solution with a pH value of 7?
Neutral
What Is the pH value of hydrochlorlic acid?
The pH value of an acid solution depends on its concentration and the temperature of the solution.
Why the pH value of salt water is 8?
The solution of pure sodium chloride is neutral.
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.
