Hello! Could you help me go trough the steps of this question? You have a solution of formic acid. The solution has been prepared by dissolving 6.90 g of pure formic acid in water to the total volume, V = 1.00 L. a) Calculate the solution pH. (I want to put this in a table, but what will happen with the initial step of the RICE table? It did not start on M, i got it in g....) b) You...

can someone please help me out with questions 1-5, please
To add more information this was given to me for a lab that used
a weak acid and we added a strong base through titration. We just
observed how the ph changes. Later we then used a buffer with a
weak acid to see how buffers affect ph change. These questions are
basically surrounded around those topics to help us prepare.
However, I'm kinda confused about answering them because weak...

10. Calculate the pH of a 0.30 M formic acid solution. (K-1.8 x 10") Weak monoprotic acid. 11. Calculate the K, for a 0.050 M solution of HA (weak acid) if the pH = 4.65. 12. What is the pH of the solution which results from mixing 50.0 mL of 0.30 M HF(aq) and 50.0 mL of 0.30 M NaOH(aq) at 25C? (K. of F = 1.4 x 10) 13. Which of...

question 2- all 4 parts. please type orwritr clearly thank
you!
2. Buffer capacity refers to the amount of acid or base a buffer can "absorb without a significant pH change. It is governed by the concentrations of the conjugate acid and base components of the buffer. A 0.5 M buffer can "absorb" five times as much acid or base as a 0.1 M buffer for a given pH change. In this problem you begin with a buffer of known...
