*TAKE NOTE*
For question 1
Use your school’s endpoint and use it wherever you see our endpoint (15.15cm³) …and calculate with it
Replace our 15.15 in 1b and do the calculation.
If your school wants to use mine, then the chemistry teacher must submit endpoint similar to ours without much difference…eg 15.15, 15.20, 15.30, etc
NO.1
NO. 2
NO. 3
(3ai)
When drops of NaOH is added to 2cm^3 of Pb(NO3)2, a white gelatinous precipitate is formed, which is soluble in excess of it.
