If you dissolve 30.0 g of HF in 100mL of water, what is the concentration of H+ ions in this solution? (Can you figure out what the H+ concentration would be using the Ka value?) Ka=6.3*10^-4

  • Chemistry -

    Yes, the concn HF is moles/L. You get moles from g HF/molar mass and the volume is 0.1 L. Then use Ka for HF, set up an ICE chart and solve for H^+.
