WebFollows HF, with 50 M. If you don't count water itself, as HF is freely soluble in water, any solution from 0 to 50M can be achieved and this could be the highest concentration … WebThe greater the frequency, the greater the energy. That's easy - but unfortunately UV-visible absorption spectra are always given using wavelengths of light rather than frequency. That means that you need to know the relationship between wavelength and frequency. You can see from this that the higher the frequency is, the lower the … WebNitric acid in water has a pKa of -1.3 and hydrobromic acid has a pKa of -9.0.
