WebbCalculate `pH` of `10^(-7)M of NaOH` solution at `25^(@)C` (take log0.618=0.21)` WebbAnswer: Concentration of given solution is 10^-9 M NaOH is a strong base. When dissolved in water, it quickly dissociates into Na+ and OH- ions. So, concentration of [OH-] ions is 10^-9 M Since the solution also contains water, concentration of [OH-] ions from water is 10^ …
Webb4 apr. 2024 · Therefore, the concentration of hydroxide ion in NaOH = 10 − 7 × 1.1. To calculate the pH of NaOH, we need to first calculate the pOH of NaOH since it is a basic solution. The pOH of a solution can be calculated as follows: p O H = − l o g [ O H −] -- (1) … WebbNaOH being strong electrolyte completely dissociates. Total hydroxide ion concentration will be the sum of the concentrations due to the dissociation of NaOH and water. But 10 −10 is much smaller than 10 −7 and can be neglected. pOH =−log[OH −]=−log10 −7=7. …
