The polyprotic acid sulfurous acid has the following Ka values. Ka1 = 6.0 x 10-3; Ka2 = 5.9 x 10-7. Calculate the pH of a solution containing 25 mL of 0.1 M sulfurous acid when titrated with the following volumes of 0.1M KOH at 20 mL KOH; 25 mL KOH; 30 mL KOH. [Hint: pH at Equivalence Point for polyprotic acids = (pKa1 + pKa2)/2]

120,630,890

step-by-step explanation:

110+10=120,620+10=630,880+10=890

i don't know people like to fight everywhere rip.

what is the question here. i think you messed up.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
