For bromocresol green indicator, the pka of the indicator is about 4.7. Estimate the pH range over which the color change occurs for bromocresol green. What would be the effect on your results if methyl red indicator, pka = 5.0 were used during the experiment?

If you have 5.25 grams of methane (ch4), how many grams of co2 will you produce ?

What is the mass of 4 molecules of co2

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.
