CH_3COOH এর দুটি নমুনা প্রতিটি 10 ​​গ্রাম আলাদাভাবে দুটি পাত্রে নেওয়া হয়েছিল যাতে 6টি জল রয়েছে ...

Calculate the pH of a given mixtures. (a) (4g CH_(3)COOH+6g CH_(3)COONa) in 100 mL of mixture, ( K_(a) for CH_(3)COOH=1.8xx10^(-5)) (b) 5 mL of 0.1MBOH+250 mL of 0.1 MBCI , ( K_(a) for MOH=1.8xx10^(-5)) (c ) ( 0.25 mole of CH_(3)COOH+0.35 mole of CH_(3COOH=3.6xx10^(-4))

The K_(a) for CH_(3)COOH at 300 and 310 K are 1.8 xx 10^(-5) and 1.805 xx 10^(-5) , respectively. The enthalpy of deprotonation for acetic acid is 51.6 cal .

Calculate the pH at equilibrium point when a solution of 10^(-6) M CH_(3)COOH is titrated with a solution of 10^(-6)M NaOH. K_(a) for acid 2 xx 10^(-5) (pK_(a) = 4.7) (Answer given in whole number).
