The pH of sample of vegetable soup was found to be 6.5. how is this soup likely to taste?

A solution of weak acid HA was titrated with base NaOH. The equivalent point was reached when 40 mL. Of 0.1 M NaOH has been added. Now 20 mL of 0.1 M HCl were added to titrated solution, the pH was found to be 5.0 What will be the pH of the solution obtained by mixing 20 mL of 0.2 M NaOH and 20 mL of 0.2 M HA?

A 1.025 g sample containing a weak acid HX (mol. Mass=82) is dissolved in 60 mL. water and titrated with 0.25 M NaOH. When half of the acid was neutralised the pH was found to be 5.0 and at the equivalence point the pH is 9.0. Calculate mass precentage of HX in sample :

The acid dissociation constant of uric acid is K_(a)=4.0xx10^(-6) M. The pH of a sample of urine is 6.0. What is the ratio of concentration of urate ion to uric acid in the urine?

Two bags contain 6 red and 3 black, 5 red and 5 black balls. One ball is drawn at random from one of the bags and found to be red. Find the probability that it was drawn from the second bag.

The decomposition of N_2 O_5 in carbon tetrachloride solution has been found to be first order with respect to N_2 O_5 with rate constant, k-6.2xx10^-4s6-1 N_2 O_5(G)rarr2NO_2(g)+1/2O_2(g) Calculate the rate of reaction when [N_2 O_5]=2.50mol L^-1

A sample of 16 g charcoal was brought into contact with CH_(4) gas contained in a vessel of 1 litre at 27^(@) C . The pressure of gas was found to fall from 760 to 608 torr. The density of chacoal sample is 1.6 g//m^(3) . What is the volume of the CH_(4) gas adsorbed per gram of the adsorbent at 608 torr and 27^(@)C ? 125 L//g , 16.25 mL//g , 26 mL//g , none of these .
