C6O2H8, Ka = 1.7 x 10-5
calculate pka
pKa = -log Ka
To calculate pKa, you need to take the negative logarithm (base 10) of the acid dissociation constant (Ka).
In this case, the given Ka value is 1.7 x 10^-5.
Using the formula: pKa = -log10(Ka),
pKa = -log10(1.7 x 10^-5)
To simplify the calculation, you can convert 1.7 x 10^-5 into a decimal number by moving the decimal point 5 places to the left:
pKa = -log10(0.000017)
Now, calculate the logarithm:
pKa = -(-4.77)
pKa ≈ 4.77
