A 5.0 M solution of HNO3 is titrated with 0.3 M NaOH. Identify the species that have the highest concenttrations in the solution being titrated halfway to the equivalence point.

A 25.15 ml of 0.35 m HNO3 was titrated with an unknown concentration of NaOH. The endpoint was reached when 29.35 ml of NaOh were delivered. Find the concentration of the titrant.


For my homework there are several questions like the ones above. If I understand how to do the ones above I think i can complete the other questions.

  1. For #2.
    NaOH + HNO3 ==> NaNO3 + H2O
    mols HNO3 = M x L = ?
    mols NaOH = mols HNO3(from the coefficients in the balanced equation.)
    M NaOH = mols NaOH/L NaOH

    For #1.
    Assume some volume of the 5.0 M HNO3.
    Calculate the volume NaOH needed to titrate half of it. Calculate the NO3^-, Na^+, and H2O. Actually I don't think they internd for H2O to be one of the asnwers but technically I think it is.
