Can I please have some help with this? Find the molar concentration (10^-6mol/l)
ml of stock solution :
solutiom 1 = 10.0ml Transmittance = 10% Absorbance = 0.98
2. 8.0ml Transmittance = 19% Absorbance = 0.70

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.
