The pH of an acid solution is 5.70. Calculate the K for the monoprotic acid. The initial acid concentration is 0.010 M. Be sure your answer has number of significant digits. K = 10 X S

You find a mysterious solution. You add universal indicator to it and the solution turns Yellow! What kind of solution is it and why?    A base, because it has a concentration of H+ ions less than 1 x 10^-7.   An acid, because it has a concentration of H+ ions less than 1 x 10^-7.   An acid, because it has a concentration of H+ ions greater than 1 x 10^-7.   A base, because it has a concentration of H+ ions greater than 1 x 10^-7

The quality assurance lab just received a shipment of three solutions. The lab manager asks you to verify the stock solutions and label each bottle with the solution's hydrogen ion concentration, [H*]. You first use the pH meter to determine the pH of each solution. Calculate the hydrogen ion concentration of solution #1, which has pH 2.25. Calculate the hydrogen ion concentration of solution #2, pH 7.25. which Calculate the hydrogen ion concentration of solution #3, which has pH 10.75. [H*] = I [H*] = [H] = M M M

An engineer wants to determine whether a certain pH meter is working correctly.  She uses the meter to measure the pH in 14 neutral substances (pH = 7.0) and obtains the data shown in the following table. 7.01 7.04 6.97 7.00 6.99 6.97 7.04 7.04 7.01 7.00 6.99 7.04 7.07 6.97   Is there sufficient evidence that the meter is not correctly measuring the pH?

In an aqueous solution of a certain acid the acid is 0.083% dissociated and the pH is 4.20. Calculate the acid dissociation constant K of the acid. Round your answer to 2 significant digits. K= x10 $ ? X

A solution of sodium cyanide, NaCN, has a pH of 11.30. How many grams of NaCN are in 865 mL of a solution with the same pH? Kb (CN–) = 1.7 × 10–5 mass =  ___________ g *I asked this prevously and 1.81 x 10^-12 is the wrong anwser for this question, if you get that.

Some chemical compounds are listed in the first column of the table below. Each compound is soluble in water. Imagine that a few tenths of a mole of each compound is dissolved in a liter of water.

Four solutions of an acid dissolved in water are sketched below, as if under a microscope so powerful individual atoms could be seen. The same volume of solution is shown in each sketch. Rank the solutions by the strength of the dissolved acid. That is, select 1 under the solution of the strongest acid, 2 under the solution of the next strongest acid, and so on. Note: =H,0 Solution 1 Solution 2 (Choose one) (Choose one) Solution 3 Solution 4 Submit Assignment Continue 2021 McGraw Hill LLC. All Rights Reserved.
