Answer:

Sodium

Explanation:

Sodium is a pure chemical, hence it can be represented by the single chemical symbol Na.

Water has a chemical symbol of H2O, consisting of two, and not one, symbols, H and O.

Sulfate ion consists of a sulfide ion and four oxygen ions (SO4)2-. Hence, it does not fit.

Finally, potassium chloride has a chemical symbol of KCl. Consisting of two different chemical symbols, (K and Cl), it does not fit either.

Hope this helped!

If a buffer solution is 0.190 m in a weak acid (ka = 8.2 × 10-5) and 0.590 m in its conjugate base, what is the ph?\
Lubov Fominskaja [6]
<span>You use the Henderson - Hasselbalch equation pH = pKa + log ([salt]/[acid]) pKa = -log (8.2*10^-5) = 4.081 pH = 4.081 + (0.590/0.190) pH = 4.081 + log 3.105 pH = 4.081 + 0.49206 pH = 4.573</span>
