If 0.630 grams of HNO3 molecular weight 63.0 are placed in a liter of distilled water at 25 degree Celsius what will be the pH of the solution?

What pH level is a neutral?
pH 7.0 is neutral at 25 degrees Celsius.
What is the pH of pure water at 25 C?
The pH value of pure water is 7.0 , but ground water is often acidified by gases dissolved in rain, or made alkaline by mineral deposits on the ground. This value is determined by the equation: pH=-log10([H+]) where [H+] is the concentration of hydrogen ions in the solution and log10() is the common log of the value. Auto-ionization of H2O into H+ and OH- tends to equalibrium at [H+]=1x10-7 mol/L
What is pH of ordinary water?
The pH of water is pH7
What is the chemical composition of malt extract agar?
thats a good question but unforunately i dont now the answer
What is the pH of pure water at 70 degree Celsius?
7

What scientific way to check if water is produced?
pH indicator will turn green showing a pH of 7 (neutral). or heat the liquid, if it boils at 100 degrees celsius then its likely to be water
How pepsin inactivated?
Pepsin is a digestive enzyme found in our digestive system for protein degradation.Pepsin can be irreversibly denatured at alkaline pH (pH 8.5 - 11) at room temperature. It can also be denatured by boiling at above 81 degree Celsius. The degraded form of protein is catalytically dead afterwards.
What is the pOH of pure water at 60C?
pH = -log(concentration of H+ ion) which indicates acid pOH = -log(concentration of OH- ion) which indicates base In pure water at 25 degree Celsius, concentration of H+ and OH- is equal i.e. 10^-7 mol/dm^3 so, the sum of pH and pOH is -log(10^-7) + -log(10^-7) = 7 + 7 = 14
What is the optimum pH of invertase?
50 degrees celsius 50 degrees celsius
What pH level is a neutral?
pH 7.0 is neutral at 25 degrees Celsius.
What is the pH of neutral solution at 25 degrees Celsius?
pOH= -log(0.0025) this equals +2.6. The pH scale is reversed, so 14-2.6 = +11.4. 11.4 is the answer
What is the pH of pure water at 25 C?

What is the normal range for safe drinking water?
700000 degrees farinheight
What is pH of ordinary water?
The pH of water is pH7
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
