26 & 27Question 26 5 pts When a strong acid is added to a strong base in a titration, what is expected at the equivalence point? A neutral solution with a pH - 7 A acidic solution from the strong acid A acidic solution from the conjugate acid of the strong base A basic solution from the strong base A basic solution from the conjugate base of the strong acid Question 27 5 pts Which molecule or ion below can act as a Lewis base? OPCI NH4 O KNO3 BF3
Answers
(26) Since we know that strong acid and strong base is completely sonided. A7 equivalence point (Stoichiometric point) the concentration of Htion is equals to the concentration of our ion. le [H+] = [OH-] at this point bouth ion are combine to form H₂O . which has neutral of PH 7. Ht lag) + OH(aq) —> H20 ) Hence, option first is correct. 27 since we know that - A substance, that can donate a pair of non bonding electrons (lome per elecofron) io called tewin base In the given option, Plaz can act as dewis base. because pada has a lone pair of electron
