Answer 1

According to Bronsted Lowry acid base acid are those substances which are of Ht to a base. theory forme a conjugate by the addition 1) Conjugate acid of (CH2), N = (CH3), NH+ 2) conjugate acid of C5 HSN H₂ & (& Hs NH 4 3) Conjugat acid of HcOh = H₂CO, 4) conjugate acid of H2poi = H₂ Pou are formed and conjugate base are those substance which by the removal of tt ion by an acid. & conjugate base of CHA CH₂COOH = CH₃ CH₂ Cool 6) conjugate base of HC10 = clor 7 conjugate base of Hf - f- 8) concentration of HCN = 0.049 M Ka of HCN = 619 x100 a pH = /2 pka - I loge. = I (- log 4,981010) - I log 0.049 Įx9:31 -x 1.31 = 1 (9.31 – 1,313 pH = 4

o Given! PH= 56 concentration = 0.54 M pH2 pka - logo - 5.62 (-log Ka) - £ log 0.54 -) 11.2 - - log ka - (-0.2676) 5) dog Ka -1142 +0.2676 a. Ka - 10-10.9324 = 100*0676x10-11 ka - 1.1684 X10-11
