Question 25 0.5 pts How many mLs of 0.15 M AgNO3 will react with exactly with 25.0 mL of a 0.200 M solution of NaCl (3 SF) NaCl (aq) + AgNO3 (aq) --> NaNO3 (aq) + AgCl (s) Question 26 0.5 pts How many mL of 0.115 M NaOH will react with exactly with 22 mL of a 0.210 M solution of H2SO4 (3 SF) 2 NaOH(aq) + H2SO4 (aq) --> Na2SO4 (aq) + 2 H20 (1)

Answer 1

(9-25) The given reaction is Nael (ad) + Ag NO 3 caw) NaNO3 can) + Agd(s. from the reaction it is clear that equivalent amount of Nad will react with equivalent amount of AgNO3. given data du - 250 ml strength of AgNO3 S, = 0.15 m Volume of AgNO3, VI = ? Strength of Nad, S2 = 0. 200 M Volume of Nad, v2 Nis, = V2 S2 or Vix 0.15 25 X 0.200 25 X 0. 200 0.15 33.34 ml 4. 33. 34 ml of 0.15 m AgNO3 will react. (9-26) The given reaction is - 2NaOH + H2SO4 → Na2SO4 + 2H₂O Given, Strength of waoH , Si = 0.115 m volume of Naoh, Vi= ? Strength of H2SO4, S2 = 0.270 m volume of H2500 V2 = 22 ml a diprotic acid. so it will form 2H+ and so a 2- Based on reaction above, we need 2 equivalent of NaOH to react with 1 equivalent of Hasoa, so need to multiply Hasoa by z حة و لا کر own we

org VISI 2 V2 S2 My X 0.115 = 2 X 22 X 0.210 2 X 22 X 0.210 O. 115 VI 80-35 ml = &0.35 ml of 0.115 m with 22 ml of 0.210 m NaOH will react Hasoy salm.
