How are ph and poh scales related
Did you know?
WebThe pH scale tells you whether a solution is acidic or basic. To calculate the pH, take the negative log of the hydronium ion concentration. To find the pOH, subtract the pH from 14. To find the pOH take the negative log of the hydroxide ion concentration. To find pH, subtract pOH from 14. pH is defined as the decimal logarithm of the reciprocal of the hydrogen ion activity, aH+, in a solution. For example, for a solution with a hydrogen ion activity of 5×10 (at that level, this is essentially the number of moles of hydrogen ions per litre of solution) the argument of the logarithm is 1/(5×10 ) = 2×10 ; thus such a solution has a pH …
WebFig.2-Scale showing pH and pOH value. If the pH of a solution is 4.6, calculate the pOH. We know that the sum of pH and pOH should be equal to 14. So, we can rearrange the … WebIn learning chemistry, the concentration value of hydroxyl ion represents the term known as the pOH in place of pH. pOH = − log (C OH −) If the acidity of a solution goes down by 100 fold its pH scale range goes up by two …
WebSaturation defines an equilibrium condition: the rate of solute dissolution is equal to the rate of solute precipitation; alternatively, the rate of going up into solution is equal to the rate of coming out of solution. undissolved solute ⇌ dissolved solute. This saturation depends on temperature, the properties of the solvent, and the nature ...
