What is the relationship between equilibrium constants of acid-base, complexometric, precipitation, and redox titration and the feasibility of titration? What are the similarities and differences between the four types of titration? Are there other factors that need to be considered when assessing the feasibility of titration?
A 50.00 mL sample of a citrus drink consumed 14.33 mL of 0.05136 M KOH to reach the phenolphthalein end point. Express the sample’s acidity as grams of citric acid, HOC(CH2CO2H)2, per 100 mL. Note: phenolphthalein pH range = 8.3 – 10. pKa1 = 3.13, pKa2 = 4.76, pKa3 = 6.40.

This might be a silly question, but hopefully I will be responded.
As far as I know, ions can't exist on their own, and have to bond with another ion, but it seems that they don't have to when it comes to action potential. It's always about a single ion (e.g. sodium ion entering and leaving cell on its own, not bonding to any other ion). How is this possible if an ion can't exist on its own? Am I wrong about this, or this is some kind of exception, or maybe something else?
68.1 g of a titanium complex P were dissolved in water and its ligand field splitting energy was measured as 59.05 KJ. Calculate the molar mass of P if the complex absorbs a wavelength of 733nm
