AI Thread Summary
To calculate the pH of a diluted HNO3 solution, first determine the total volume after mixing 800 mL of 0.01 M HNO3 with 700.75 mL of water, resulting in 1500.75 mL. Since nitric acid is a strong acid, it dissociates completely in solution, meaning the concentration of hydrogen ions equals the initial concentration of HNO3. The hydrogen ion concentration can be calculated by dividing the moles of HNO3 by the total volume in liters. Finally, the pH is found using the formula pH = -log[H+]. This method provides a straightforward way to find the pH of the diluted solution.

hey guys, I've just started PH, just wondering if you could show me how to do this question. thanks for any help

What is the pH of a solution made by mixing 800 mL of 0.01 M HNO3 and 700.75 mL of water?
 
Physics news on Phys.org
Nitric acid is a strong acid - what does this mean?
pH means "negative logarithm of the hydrogen ion concentration in Molarity", at least for practical purposes - Did you yet calculate the hydrogen ion concentration in your given solution?

note: the logarithm is in 'base ten'

does that mean it dissociates completely?
 
Yes, you may safely assume it is completely dissociated.
 

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
