how to find PH??????????
Answers
Answer:
To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression: pH = - log [H3O+].

Answer:
pH is determined by the concentration of H+, which is frequently summarized as [H+]. This can be calculated by the following equation:
pH=-log { left[ { H }^{ + } right] }pH=−logleft[H
+
right] or pH=log { left( frac { 1 }{ left[ { H }^{ + } right] } right) }pH=logleft(frac1left[H
+
right]right)
Conversely, the hydrogen concentration can be found by a given pH. The [H+] can be calculated by the following equation.
left[ { H }^{ + } right] ={ 10 }^{ -pH }left[H
+
right]=10
−pH
The determination of the concentration of hydrogen ions and pH will later be used to show the relationship between pH and pOH.
