An aqueous solution at 25 has a pH of 6.12. Calculate the pOH. Round your answer to 2 decimal places.

Calculate the number of moles of ethane in 100 grams

Abeaker with 2.00×102 ml of an acetic acid buffer with a ph of 5.000 is sitting on a benchtop. the total molarity of acid and conjugate base in this buffer is 0.100 m. a student adds 4.70 ml of a 0.360 m hcl solution to the beaker. how much will the ph change? the pka of acetic acid is 4.740.
