geffman1 said:does that mean just make the dissocation equation just with HNO3. well this is what i did. HNO3>NO3 + H therefore equation equals. [H][NO3]/[HNO3]=1.8e-4 therefore solving this x^2/0.1=1.8e-4 therefore i get a ph of 2.37? thansk for replying
Concentration refers to the amount of a substance present in a given volume or mass. It is typically expressed in units such as molarity (moles per liter) or weight/volume (grams per liter). To calculate concentration, divide the amount of substance by the volume or mass of the solution.
pH is a measure of the acidity or basicity of a solution on a scale from 0 to 14. It is calculated by taking the negative logarithm of the hydrogen ion concentration in moles per liter. The formula for pH is pH = -log[H+], where [H+] is the hydrogen ion concentration.
The concentration and pH of a solution are directly related. As the concentration of hydrogen ions increases, the pH decreases, making the solution more acidic. On the other hand, as the concentration of hydrogen ions decreases, the pH increases, making the solution more basic.
To convert between units of concentration, you can use conversion factors based on the molar ratio of the substances involved. To convert between concentration and pH, you can use the formula pH = -log[H+]. You can also use online calculators or tables to make conversions easier.
Temperature can affect both concentration and pH. Changes in temperature can cause substances to dissolve more or less readily, which can affect the concentration of a solution. Additionally, pH is temperature dependent, with higher temperatures leading to a decrease in pH due to increased dissociation of hydrogen ions from water molecules.
