100 times higher h* concentration
The main difference between pH 4 and pH 6 is the concentration of hydrogen ions in the solution. A pH of 4 indicates a higher concentration of hydrogen ions compared to a pH of 6, which means the solution with pH 4 is more acidic than the solution with pH 6.
pH 8: [H+] = 10^-8 M pH 6: [H+] = 10^-6 M 10^-6 / 10^-8 = 10^2 = 100 Answer is 100 times fewer
The concentration of a solution at a pH of 4 is higher in hydrogen ions than a solution at a pH of 6. pH is a logarithmic scale of hydrogen ion concentration, so each unit change in pH represents a 10-fold difference in ion concentration.
The pH of dettol is 4-9 so it takes up most of the pH scale.
Sodium bisulfite typically results in a solution with a pH between 4 and 6, as it is an acidic compound.
The main difference between pH 4 and pH 6 is the concentration of hydrogen ions in the solution. A pH of 4 indicates a higher concentration of hydrogen ions compared to a pH of 6, which means the solution with pH 4 is more acidic than the solution with pH 6.
4 to 6 is the pH of pine trees
is PH 4-6
A pH meter must be standardized because it measures relative potentials and thus relative pH. It is necessary to know to what the measurement is relative. A standard must be measured and the meter set to the known value for this standard. The pH values of other solutions are then measured relative to this standard.
pH 8: [H+] = 10^-8 M pH 6: [H+] = 10^-6 M 10^-6 / 10^-8 = 10^2 = 100 Answer is 100 times fewer

3/4-6
It is the measure of relative acidity and alkalinity
The pH of dettol is 4-9 so it takes up most of the pH scale.
The pH after mixing two buffers can be calculated using the Henderson-Hasselbalch equation, pH = pKa + log([A-]/[HA]), where [A-] is the concentration of conjugate base and [HA] is the concentration of the weak acid. Given pH of 4 and 6, the pKa can be determined and used in the equation to find the final pH value after mixing.
False. The concentration of H+ ions is not determined by the pH values alone. It depends on the actual H+ ion concentration in the solution. pH is a measure of the concentration of H+ ions in a solution, but the relationship between pH and H+ ion concentration is not strictly linear.
Sodium bisulfite typically results in a solution with a pH between 4 and 6, as it is an acidic compound.
