Acid-Base Equilibria
The adhering to troubles are extracted from T. L. Brown, H. E. Lemay, B. E. Bursten, & J. R. Burdge, Chemistry: The Central Science, Ninth Edition, Chapter 16. To see the remedy to a trouble or to return from the service, click on the variety of the trouble. 24 )Think about 2 remedies, option An and also option B. [H+]
inremedy A is 500 times higher than that in remedy B. What is the distinction in the pH worths of both services? 34)Compute the pH of each of the complying with solid acid services:( a)0.0575 M HNO 3(b)0.723 g HClO 4
in
2.00 L of remedy (c)5.00 mL of 1.00 M HCl weakened to 0.750 L(d )a mix developed by including
50.0 mL of 0.020 M HClto 125 mL
of 0.010 HI 38) Determine the focus of a liquid option
of Ca( OH)2 that has a pH of 12.00. 46) A
0.100 M remedy of chloroacetic acid(ClCH 2 COOH )is 11.0%ionized. Utilizing this info
compute
, [ClCH 2 COO-], [H+], [ClCH 2 COOH], as well as K a for chloroacetic acid.
54) The energetic component in pain killers is acetylsalicylic acid(HC 9 H 7 O 4 ), a monoprotic acid with a K a=3.3 x 10 -4 at 25 ° C. What is the pH of a service gotten by liquifying 2 extra-strength pain killers tablet computers, including 500 mg of acetylsalicylic acid each, in 250mL of water? 66 )Determine the molar
focus of OH-ions in
