pH = -log(Concentration)

pH = -log(3)

pH = -(0.477121255)

What should be the pH of 3M KCl solution?

I believe it should be 7.0. Here's an example of 3M KCl made for sale with the specs, showing a pH of 7.0


Why pH probes always kept immersed in 3M Kcl solution?

I just got done talking with a vendor for pH probes and he explained that the KCl solution helps facilitate the measurement of the hydrogen ions with the electrode. It will actually seep out in small quantities from the tip which is a membrane.


How much kcl require for prepaire 3M kcl?

Molar mass of KCl = 74.55g/mol.ie, if you dissolve 74.55g KCl in 1litre (1000 ml) of water, it will be 1M KCl solution.If you want to make 3M KCl solution,Dissolve 3 ×74.55 = 223.65g KCl in 1litre (1000 ml) of water.If you want to make different molar solutions of KCl, just calculate as per below given equation.Weight of KCl to be weighed =Molarity of the solution needed × Molecular weight of KCl (ie, 74.55) × Volume of solution needed in ml / 1000.To prepare 3M KCl in 1 litre, it can be calculated as follows,3 mol × 74.55 g/mol × 1000 ml / 1000 ml = 223.65gByPraveen P Thalichalam, Kasaragod (Dist), Kerala.


Why DO you add KCl in dm water for measurement of pH?

Potassium chloride (KCl) is often added to distilled water to create a standard reference solution for pH measurements, known as a "buffer solution." This helps stabilize the pH of the solution and maintain its pH value when acids or bases are added. This ensures that the pH reading is accurate and reliable.


Is there any pH change when KCl dissolves in water?

No there is no pH change KCl+H20--> K2O + HCl neither OH- or H+ is formed, which would make it either more acidic or more basic. KCl is a salt


What is the pH KCl?

1. Identify (a) through (d) as reactants or products. Type your answers in the spaces provided: (a) (b) (c) (d) KOH + HCl KCl + H2O


Is the combination of HCl and KCl considered a buffer solution?

Yes, the combination of HCl and KCl is considered a buffer solution because it contains a weak acid (HCl) and its conjugate base (KCl), which can help maintain a stable pH when small amounts of acid or base are added.


How many moles of KCl are contained in 0.635L of 2.2M KCl?

moles KCl = ( M solution ) ( V solution in L )moles KCl = ( 2.2 mol KCl / L solution ) ( 0.635 L of solution )moles KCl = 1.397 moles KCl


What colour is KCl solution?

A potassium chloride (KCl) solution is colorless.


How many moles of KCl are contained in 1.7L of a 0.83M KCl solution?

moles KCL = ( M solution ) ( L of solution )moles KCl = ( 0.83 mol KCl / L ) ( 1.7 L ) = 1.41 moles KCl


Is the solution a buffer or not, considering the presence of both HCl and KCl?

Yes, the solution is a buffer because it contains both a weak acid (HCl) and its conjugate base (KCl), which can help maintain a stable pH when small amounts of acid or base are added.


How much KCL is required for 500mM KCL solution?

To prepare a 500mM KCl solution, you would need to dissolve 74.55 grams of KCl in enough solvent to make 1 liter of solution.
