pH = -log(Concentration)
pH = -log(3)
pH = -(0.477121255)

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

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
A potassium chloride (KCl) solution is colorless.
moles KCL = ( M solution ) ( L of solution )moles KCl = ( 0.83 mol KCl / L ) ( 1.7 L ) = 1.41 moles KCl
