At pH 4.98, the Percentage of Ionized Species

A solution’s pH is an indicator of its acidity. Lower pH indicate a less acidic solution. It is considered that pH 4.98 represents a moderately acidic solution. Therefore, it can be used to calculate the percentage of ions present. This percentage is important in understanding the behaviour of a solution, and can be determined using the Henderson-Hasselbalch equation (Kahle & Wick, 2016). This equation states that the ratio of the concentrations of a protonated and deprotonated species is equal to the negative base-10 logarithm of the acid dissociation constant (Kahle & Wick, 2016). Therefore, the percentage of ionised species can be calculated as the fraction of the total concentration of the species which is in the ionised form (Gan & Vaz, 2018). With the Henderson-Hasselbalch equation and the acid dissociation constant for the species in question, the fractions of the protonated and deprotonated species can be determined. The fraction of ionized species can then be calculated by subtracting the proportion of protonated species from that of total species. The fraction of the ionized species can be multiplied with…
