hi forum,
would nebody be able to help me solve this problem?
0.18mol of potassium cyanide (KCN) was dissolved in 1.00L of a solution in which the pH was held constant at 9.70 at a temperature of 298K.
the equilibrium concentration of CN- was 0.13M.
Calculate Ka for the weak acid HCN...

If i have a reaction between iron(II) sulphate, sulphuric acid and potassium permanganate (KMnO4), what are the ions present in the salt??!
similarly, if i have a reaction between nitric acid and copper solid, what are the ions present in salt?
can nebody help me? thanks :)
Ok everyone I have a task for homework which asks me to: Determine the parameters for a rope suitable for you to use to make a safe 40m jump.
At the moment, I'm unsure of the physics behind bungee jumping, but I know the parameters that I'd have to consider would be the length of the rope...
