Answer 1

Strony reid is fully dissociated to give Ht. ☆ HI s strong reid HI caps - H+ (aq) + I Tags PH = -log[nt] pH = -log 2.9x102 = 1.54 ③ 0.114m Huloy n a Helou is a strong acid pH = -log 0.114 = 0.94 ③ Both He & Hciou are strong acids, hence total [ut]= (5.7x10²) + ( 3.6x162) - 9.3x10-2 PH = -log [st] - loz 9.3x102 = 1:03 1.85). He by mass let mass of solution = loog wass of ha= 1.859 Volume of solution = mass 0 density

Volume - 99.0 ml Toog 1-olgunl Iml= 10 l Volume = 0.099 l no of mole- mass molar mass mole of rel= 1.85 = 0.0506 365 Molarily a no of moles of soluti Volume of solution (l) 0.0506 0.099 [hu]= [ht] =0.511m pu- lg [at] = -log 0.511 -0.003
