a) Find the pH of a liquad if the concentration of hydrogen ions (H+) is 7.9 * 10^-9 mole per liter.
b) Find the concentration of hydrogen ions (H+) if the pH of the liquad is 3.2
Thank you Alan!
pH is -log to base 10 of H+ concentration, so:
a. pH=−log10(7.9×10−9)⇒pH=8.102372908709558
or pH≈8.1
b. conc=10−3.2⇒conc=0.0006309573444802
conc of H+ ≈ 6.3*10-4
+564
