Question

Match the pH value 1,7,10,13 to the solution given below milk of magnesium Gastric juice Brine aqueous sodium hydroxide

Answer 1

Answer:

• pH of MOM = 10 (base)
• pH of gastric juice = 1 (acid)
• pH of brine = 7 (neutral)
• pH of sodium hydroxide = 13 (base).

More:

• The more the concentration of H+ (aq) in a given aqueous solution, the less the value of its pH. Same thing happens for pOH [measured by concentration of OH- (aq) conc.].
• Less then 7 pH = Acid/More than 7 = Basic.
• Formula: $\rm pH = - \log [{H}^{+}]$.
