undissociated การใช้

• The second option is to re-evaporate partially or completely undissociated.
• I would argue that hydrochloric acid is in fact hydronium chloride, since there is very little actual undissociated HCl present in a bottle of hydrochloric acid!
• It has been well demonstrated that the state of the organic acids ( undissociated or dissociated ) is extremely important in determining their capacity to inhibit the growth of bacteria.
• A weak electrolyte is a substance whose solute exists in solution mostly in the form of molecules ( which are said to be " undissociated " ), with only a small fraction in the form of ions.
• This simple model predicts activities of many species ( dissolved undissociated gases such as CO 2, H 2 S, NH 3, undissociated acids and bases ) to high ionic strengths ( up to 5 mol / kg ).
• This simple model predicts activities of many species ( dissolved undissociated gases such as CO 2, H 2 S, NH 3, undissociated acids and bases ) to high ionic strengths ( up to 5 mol / kg ).
• The first row, labeled I, has the initial conditions : the " nominal concentration " of acid is C a and it is initially undissociated, so the concentrations of A  " and H + are zero.
• Here, is the molar concentration of the undissociated weak acid, is the molar concentration ( molarity, " M " ) of this acid's conjugate base and is where is the acid dissociation constant, that is:
• If " " is the fraction of dissociated electrolyte, then " " is the concentration of each ionic species . must, therefore be the fraction of " undissociated " electrolyte, and the concentration of same.
• Acids with a p " K " a value of less than about  " 2 are said to be strong acids; the dissociation of a strong acid is effectively complete such that concentration of the undissociated acid is too small to be measured . p " K " a values for strong acids can, however, be estimated by theoretical means.
