Which of the following could be reasons why litmus is an ideal indicator in the titration of HCl with NaOH but not a good choice in the titration of CH3CO2H with NaOH? a) The equivalence point for the titration of HCl with NaOH occurs within the color change of litmus.
b) The pH of the equivalence point for the titration of CH3CO2H with NaOH occurs outside the color change of litmus.
c) All of the CH3CO2H is consumed before the color change of litmus occurs.
d) The HCl reacts directly with the litmus to change its color.

12. calculate the hydroxide ion concentration of a solution with ph = 3.25. show all calculations leading to an answer

Imagine if during the cathode ray experiment, the size of the particles of the ray was the same as the size of the atom forming the cathode. which other model or scientific observation would have also been supported? 1. this would support dalton's postulates that proposed the atoms are indivisible because no small particles are involved. 2. this would support bohr's prediction about electrons moving in orbits having specific energy. 3. this would support bohr's prediction about electrons being randomly scattered around the nucleus in the atom. 4. this would support dalton's postulates that proposed that atoms combine in fixed whole number ratios to form compounds.

Calculate the h3o+ concentration in a solution of acetic acid if the concentration of molecular acetic acid present at equilibrium is 9.97x10-3 m and k for the dissociation is 1.86x10-5. ch3cooh(aq)+h2o(l)+> h3o+(aq)+ch3coo-(aq) show me how to get the answer.
