What is the pH value of KOH?

a solution of koh (strong base) has a pH= 12.64 what is the concentration of koh? Now use the pOH equation.

What is the pH of 10 7 M NaOH?

7.01
of 10−7M NaOH. is: A) 7.01.

What is the pH of 3.0 M KOH?

pH = 14 – pOH = 14 – 1.48 = 12.52. Therefore, the pH of a 0.033 M KOH solution would be 12.52.

What is the pH of 0.0001 KOH?

pH=14-pOH=14-4=10.

What is the pH of 1.0 10 − 7 M HCL?

Explanation: This is a very low concentration so we must take into account the dissociation of water rather than use 10−7 as the H+ concentration, which would give a pH of 7.

What is the hydrogen ion concentration of 0.1 N CH3COOH?

The hydrogen ion concentration of 0.1 N solution of CH_(3)COOH, which is 30\% dissociated, is. [H+]=c×α=0.1×30100=0.03M.

What is the pH of a 0.5 M?

Hence, we can conclude that pH of given 0.5 m aqueous solution of HF is 2.

What is the range of pH of KOH solutions?

Range of ph of koh solutions between 0.1 M – 0.0001 M If concentration of KOH is 0.1 M, pH value may be 13. If concentation is 0.0001 M, pH value will be 10. Therefore, pH range of KOH solution will be 10-13.

What is the difference between pH of NaOH and Koh?

Both NaOH and KOH are strong bases and dissociate completely in the water. So when NaOH and KOH concentrations are equal, after the dissociation, hydroxyl ion concentration is also same. Therefore pH of both solution is equal. But, basic strength of KOH is much higher than NaOH.

How to calculate OH- concentration from pH value?

If pH value is high, we know, pH value will completely depend on the concentration of NaOH. Otherwise we have to consider dissociation of water to calculate OH – concentration. If pH is higher (above 9), we can directly calculate OH – concentration from pOH = -log 10 [ (OH -)]. To find the pOH, use the relationship of pH + pOH = pKa.

What is the initial concentration of Koh in water?

Theory 1: KOH dissociates completely in the water to K + and OH – ions. Theory 2: Due to complete dissociation, initial concentration of KOH is equal to OH – concentration. In the laboratory, there is a aqueous potassium hydroxide solution which was prepared by a student.
