Concept Introduction:
The concentration of hydrogen ions in a solution determines the acidity of a solution. If concentration of hydrogen ion is more than the solution is more acetic, if it is low, solution is less acidic.
The pH of solution is defined as negative log of hydrogen ion concentration thus, it can be calculated as follows:
Here,
Similarly, pOH of a solution is defined as negative log of hydroxide ion concentration thus, it can be calculated as follows:
Here,
pH and pOH of a solution are related to each other as follows:
In a pH scale, if the value of pH is below 7 the solution is said to be acidic in nature, if the pH value is above 7 it is said to be basic in nature. At pH 7, the solution is neutral.

- Common Acids and Bases Use the data in Table 18.8 to answer the following questions. Which substance is the most basic? Which substance is closest to neutral? Which has a concentration of H+=4.01010M ? Which has a pOH of 11.0? How many times more basic is antacid than blood?arrow_forwardRepeat the description for Question 4, but use a weak acid rather than a strong one.arrow_forwardIonization of the first proton from H2SeO4 is complete (H2SeO4 is a strong acid); the acid-ionization constant for the second proton is 1.2 102. a What would be the approximate hydronium-ion concentration in 0.150 M H2SeO4 if ionization of the second proton were ignored? b The ionization of the second proton must be considered for a more exact answer, however. Calculate the hydronium-ion concentration in 0.150 M H2SeO4, accounting for the ionization of both protons.arrow_forward
- Using the acid ionization constant information given in Table 10-3, indicate which acid is the stronger in each of the following acid pairs. a. H3PO4 and H2PO4 b. H3PO4 and H2CO3 c. HPO42 and H2PO4 d. HC2H3O2 and HCNarrow_forwardTable 13-4 lists the stepwise Ka values for some polyprotic acids. What is the difference between a monoprotic acid, a diprotic acid, and a triprotic acid? Most polyprotic acids are weak acids; the major exception is H2SO4. To solve for the pH of a solution of H2SO4, you must generally solve a strong acid problem as well as a weak acid problem. Explain. Write out the reactions that refer to Ka1 and Ka2 for H2SO4. For H3PO4, Ka1 = 7.5 103, Ka2 = 6.2 108, and Ka3= 4.8 1013. Write out the reactions that refer to the Ka1, Ka2and Ka3equilibrium constants. What are the three acids in a solution of H3PO4? Which acid is strongest? What are the three conjugate bases in a solution of H3PO4? Which conjugate base is strongest? Summarize the strategy for calculating the pH of a polyprotic acid in water.arrow_forward||| = O ACIDS AND BASES Determining the strength of acids from a sketch 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. Note: 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. = H₂O Solution 1 (Choose one) Explanation Solution 3 (Choose one) Check ▼ ▬▬▬▬▬ Solution 2 (Choose one) ▼ Solution 4 (Choose one) 0/5 X spv7Aqws 3 Allie © 2023 McGraw Hill LLC.

What is the ratio (to one decimal place) of bicarbonate (conjugate base) to carbonic acid (weak acid) in the blood's buffering equilibrium? Note, the K₂ of carbonic acid is 4.27 x 10-7. Write your answer this way: # to 1 Done Clear Incorrect. The ratio is 10.7 to 1, indicating that there is 10 times more bicarbonate than carbonic acid.

During this same year, the United States had an increase in the burning of fossil fu- els to power homes and vehicles. Which statement best describes how these two occurrences are related? The United States' emissions of sulfur dioxide and nitrogen dioxide increased as a result of a decrease in the burning of fossil fuels to power homes and vehicles, and wind pat- terns caused these emissions to travel, leading to the formation of acid precipitation in other areas. The United States' emissions of sulfur dioxide and nitrogen dioxide increased as a result of an increase in the burning of fossil fuels to power homes and vehicles, and wind pat- terns caused these emissions to travel, leading to the formation of acid precipitation in other areas.
