People conduct scientific investigations by formulating a hypothesis and observing the results. They then draw conclusions from those results and then share those conclusions with the larger scientific community.
Answer:
1.93
Explanation:
Moles of C
H
COOH = 38/1000 × 0.50 = 0.019mol
Moles of C
H
COONa = Mass/Molar mass = 2.64/144.10 = 0.018321mol
Final pH = pKa + log([C
H
COONa]/[C
H
COOH]
= -log Ka + log(mols of C
H
COONa]/mols of C
H
COOH
= -log(6.5 × 10^(-5)) + log (0.018321/0.019)=4.17
change in pH = final - initial pH
= 4.17 - 2.24
=1.93
