Answer #1

14..The formula for pH is pH = -log[H+]. This means pH is the negative base 10 logarithm ("log" on a calculator) of the hydrogen ion concentration of a solution. To calculate it, take the log of the hydrogen ion concentration and reverse the sign to get the answer. I.e 0.778

For acidic solution Nd basic solutiin i need how much HCl and NaOH should be added because for calculation of pH after addition of HCl or NaOH the formula is To calculate the specific pH of a given buffer, you need to use the Henderson-Hasselbalch equation for acidic. Buffre pH = pKa + log10([A-]/[HA])," where Ka is the "dissociation constant" for the weak acid, [A-] is the concentration of conjugate base and [HA] is the concentration of the weak acid.
