Titration of polyprotic acids/bases and mixtures

0 1M solution of phosphoric acid titrated with 0 1M solution of strong base pK a1 =2 15 pK a2 =7 20 pK a3 =12 35 Titration curve calculated with BATE - pH calculator In the case of phosphoric acid first two protons are similar in strength to protons in maleic acid thus initially titration curve looks similar with two separate end points

Strong vs Weak Acids and Bases

NH 3 (ammonia) is not a strong base It is considered a weak base because in solution it does not generate many hydroxide ions Although ammonia has no oxygen atoms in its molecule and therefore can't dissociate into hydroxide ions directly when dissolved in water the NH 3 molecule attracts a proton to form an ammonium ion NH 4 The proton is taken from the H 2 O water molecule leaving an

What is the pH of a 0 050 M NaOH solution?

The pH is about 12 7 NaOH is a strong base meaning it will dissociate basically completely in solution to form Na^+ and OH^- ions in solution One mole of OH^- ions is created for every mole of NaOH that is dissolved If it's a 05 M solution of NaOH then it can also be interpreted to be a 05M solution of OH^- pOH (The pH scale for bases) can be found by taking the negative logarithm of

Heat of neutralisation of lioh and hcl at 25c is 34 868kj

When a strong acid and weak base is used it comes out to be somewhat lower than 57 1 KJ mol ⁻in this case it is 34 868 KJ mol ⁻ the reason for this lower energy is that some amount of energy is utilized in the complete ionization of weak base that is LiOH So the heat of ionization of LiOH=57 1-34 868
