A patient with respiratory alkalosis has a blood plasma pH of 7.50. What is the [OH-] of the blood plasma? Express your answer to two significant figures and include the appropriate units.

1a) The hydronium ion concentration of an aqueous solution of 0.394 M diethylamine (a weak base with the formula (C2H5)2NH) is[H3O+] = ______ M. b) The pOH of an aqueous solution of 0.394 M ethylamine (a weak base with the formula C2H5NH2) is ______

Each row of the table below describes an aqueous solution at about 25 °C. Complete the table. That is, fill in any missing entries in the second and third columns. Round your entries for your entries for pH to 2 decimal places. solution [H,O*] PH x10 [H,O] to: -12 A 6.3 x 10 mol/L B 0- mol/L 0.0016 mol/L C 7.27 X G to 2 significant digits, and

[H+] = .0001 [H+] = 0.0030 [ОН-] — 8.6 е -8 РОН 3 4.9 pH = 7.3 %3D At 37 degrees C, which of these solutions can we say is nearly neutral?

f the pOH of a solution is 10.59, what is the H3O+ concentration in the solution?   Write the answer in scientific notation with 2 sig.dig.  For example if your answer is 3.49x10^3, write down 3.49e+3. The +/- signs are important!  Also, make sure there are no spaces between values, otherwise the answer will be considered incorrect!

What is the concentration of OH- in a sample of blood with a pH of 7.36?  Express your answer in scientific notation with two significant figures

Each row of the table below describes an aqueous solution at about 25 °C. Complete the table. That is, fill in any missing entries in the second and third columns. Round your entries for H,O' to 2 significant digits, and your entries for pH to 2 decimal places. solution pH K10 A 6.2 x 10 mol/L |mol/L 8.48 7.8 x 10 mol/L

In 0.238 M (aq) solution of sodium hydroxide,NaOH How many grams of NaOH are dissolved in 23.46 mL How many individual hydroxide ions (OH-) are found in 23.46mL
