How do you use the 5% rule in chemistry?
Re: 5% rule
So you find your x value through the approximation method then divide by your initial amount of weak acid or base and multiply by 100. If the number calculated is greater than 5 then the quadratic formula should be used to solve for x. (x/[HA]) x 100 = some percent.
What is the rule of 1000 in chemistry?
Reactions that result in a mixture of products and reactants have K around one, and as a rule of thumb we say if K is between and thousand and a thousandth, (1,000>K>1/1000), both reactants and products exist once the reaction is over.
How do you use the approximation method?
The Method of Successive Approximations
1assume an approximate value for the variable that will simplify the equation.2solve for the variable.3use the answer as the second apporximate value and solve the equation again.4repeat this process until a constant value for the variable is obtained.
The general expression: Kp = Kc(RT) ?n can be derived where ?n = moles of gaseous products - moles of gaseous reactants.
