WebThe dissociation constant of pure water is 0.172 pH/10ºC. This mean at 50 ºC pure water has a pH of 6.61, while at 0 ºC it will have a value of 7.47 pH. The amount of temperature change involved and the critical nature of the measurement dictate if this effect must be compensated for or not. (Figure 8) Web11 Apr 2024 · A small amount of this concentrated TiO 2-water “mother ink” (30 mg) was diluted in a water and IPA (2-propanol) mixture (0.47 g water, 1.7 g IPA). The diluted ink was bath sonicated for 5 min prior to spraying. The as-received Nafion membrane was removed from the plastic backing and soaked in DI water over night.
