Determine the PH of 0.300M sodium hydrogen phosphate, Na2HPO4.phosphoric acid, H3PO4,contains Ka₁ = 7.5 × 10⁻³ ,Ka₂ = 6.2 × 10⁻⁸, and Ka₃ = 4.2 × 10⁻¹³

i need mutiple choices

c (diamond),

sio2 (quartz)

answer: option (a) is the correct answer.

explanation:

the measurement of hydrogen ions in a solution is known as ph.

if ph of a solution is less than 7 then the solution is acidic. if ph of a solution is greater than 7 then the solution is basic.

when the ph of a solution equals 7, then the solution is considered as neutral.

the ph of pure water is 7, therefore, it means that concentration of hydronium ions equals that of hydroxide ions.
