12.16 mL of a solution of a monoprotic strong acid of unknown concentration requires 13.14 mL of a solution of 0.185 M NaOH to reach the endpoint. What is the concentration of the strong acid solution in mol/L? Report your answer to 3 decimal places and only report the numerical value (no units). Do not use scientific notation to answer this question.

Calculate the %(m/v) of hydrochloric acid using the molar concentration you found. Shows calculations. Records final answer to correct significant digits. Records the concentration with the appropriate units. The molar concentration I found was 0.1M.

A 1.74 M solution of nitrous acid is prepared. Find the percent ionization. A second solution is prepared in the same manner except the solution also contains 0.40 M potassium nitrite. Find the percent ionization. How much did the percent ionization decrease with the addition of the common nitrite ion? (First value minus second value. Should be a positive number) (0.01) Use the table of ionization constants from class as needed. Type your answer.....

Two students perform a chemical reaction between an acid and a base with equal strength. They collect the following data after the chemical reaction has stopped: Blue- Remained Blue Litmus paper Red- Remained red IpH meter 7. Phenolphthalein Clear Which of the following is a conclusion that can be made about the solution after the reaction has finished? Not enough information to conclude. The number of hydrogen ions is greater than the number of hydroxide ions O The number of hydrogen jons equals the number of hydroxide ions O The number of hydrogen ions is less than the number of hydroxide ions

#2, #3 - Thumbs up if you do it correctly!!

what are the products Please dont give hand written solution

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. The important chemical species that would be present in this solution are written in the second column of the table. Use the checkboxes to classify each compound. compound HCI W Ba (OH), HC,H,O, KCI Explanation patric(most common) 1 Other place . с important species present when dissolved in water E н,о, ст. н.о Ba, OH, H₂O но, с.н,о.. нс.н, о,, H,о K, CI, H₂O Check $ 4 R type of compound (check all that apply) ionic molecular strong weak strong weak acid acid base base Speciation is happening because the two groups split and live in other places 0 % 5 0 0 0 0 0 T 0 0 0 G Search or type URL 0 0 0 0 X Y 0 0 0 0 S & 0 © 2023 McGraw Hill LLC.
