A buffer solution is 0.310 M in H2SO3 and 0.304 M in NaHSO3. If Ka1 forH2SO4 is 1.7e-2 , what is the pH of this buffer solution

pH of the buffer solution is 1.76

Explanation:

To find the pH of a buffer we can use Henderson-Hasselbalch equation:

pH = pKa + log [A⁻] / [HA]

Where pKa is -log Ka= 1.77 And [A⁻] is molar concentration of conjugate base, NaHSO₃ and [HA] molar concentration of weak acid, H₂SO₃

Replacing values of the problem:

pH = 1.77 + log [0.304M] / [0.310M]

pH = 1.76

the answer is   c.) 1575 j.

explanation:

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
