What is the pH of 3M KCl solution?
pH = -log(Concentration)pH = -log(3)pH = -(0.477121255)pH = -0.477121255
What is the final concentration of cl ion when 250 ml of 020 M cacl2 solution is mixed with 250 ml of 040 M kcl solution?
Start with CaCl2. 250ml of 0.20M solution will give (0.2/1000)*250 moles = 0.05 moles. However, CaCl2--> Ca2+ + 2Cl- (1:2 reaction) so 0.05moles of CaCl2 will give 2* 0.05 moles cl ions =0.1moles. KCl will give (0.4/1000)* 250 moles =0.1 moles Since KCl--> K+ + Cl- (1:1 reaction) so 0.1 moles KCl will give 0.1 moles Cl ions. Add the 2 together so 0.1moles + 0.1 moles = 0.2 moles in total.
What is the Ph of CaCl2?
5 - 6 its an acid but a weak one coz its a salt =)
What 1 molar aqueous solution has the highest number density of ions 1 Glucose 2 CaCl2 3 NaNO3 4 KCl?
NaNO3
How do you write a balanced equation for the precipitation of calcium carbonate from potassium carbonate and calcium chloride?
The chemical equation is:K2CO3 + CaCl2 = CaCO3(s) + 2 KCl
What is the pH of 3M KCl solution?
pH = -log(Concentration)pH = -log(3)pH = -(0.477121255)pH = -0.477121255
What is the complete balanced equation for the reaction between CaCO3 and KCl?
K2CO3 CaCl2
What is the difference between KCL and KVL?
KCL calculate current . KVL calculate voltage drop.
Why DO you add KCl in dm water for measurement of pH?
we do add KCl to water for the measurement of pH to prevent CO2 from dissolution in water and forming of H2CO3
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
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 are the salts of the sea?
The most important salt in the sea water is sodium chloride; other salts present are KCl, CaCl2, MgCl2.
What are the six inorganic salts?
there are many inorganic salts. NaCl, KCl, CaCl2 etc....organic compounds contain carbon and hydrogen

What is individual use of compositions in frog ringer solution?
to bathe the animal tissues, to prolong the survival time of excised tissue,used as source of electrolytessodium chloride-for maintaining isotonicity glucose-source of energy(atp) kcl,cacl2,mgcl2-provide electrolytes Nahco3- maintain ph
