Concept explainers
(a)
Interpretation:
The balanced equation for equation 8.15 has to written.
Concept introduction:
Balanced equation:
If the chemical equation contains the equal number of atoms and charge in both reactant and product side is known as balanced equation.
(b)
Interpretation:
Wheather the bicarbonate ion functioning as acid (or) base has to be identified.
Concept introduction:
Acid -Base reaction:
The reaction between acid and base to produce a salt is called acid-base reaction.
Strong Acids: Acids that dissociates into ions completely which results in easy donation of protons are considered as strong acids. Strong acid forms weaker conjugated base.
Weak Acids: Acids that do not easily dissociate into ions completely which has difficulty in proton donation are considered as weak acids. Weak acid forms stronger conjugated base

Chemistry In Context
- Explain the difference between a monoprotic acid, a diprotic acid, and a triprotic acid. Give an example of each.arrow_forward. Why do scientists tend to express the acidity of a solution in terms of its Ph, rather than in terms of the molarity of hydrogen ion present? How is pH defined mathematically?arrow_forwardFor an acid-base reaction, what is the reacting species (the ion or molecule that appears in the chemical equation) in the following bases? (a) barium hydroxide (b) trimethylamine (CH3)3N (c) aniline, C6H5NH2 (d) sodium hydroxidearrow_forward
- Draw a curve similar to that shown in Figure 14.23 for a series of solutions of NH3. Plot [OH-] on the vertical axis and the total concentration of NH3 (both ionized and nonionized NH3 molecules) on the horizontal axis. Let the total concentration of NH3 vary from 11010M to 1102M.arrow_forwardThe hydrogen concentration of a solution is 1 x 10-4 M. What is the pH? pH = ____________ Is this an acid, base or neutral? base acid neutralarrow_forward7. Cite at least 3 examples of bases. b. a. C. 8. What is a substance that is capable of donating a proton? 9. What is a substance that is capable of accepting a proton? 10. Water is amphoteric, which meansarrow_forward
- The hydroxide ion concentration in household ammonia is 3.2 × 10–3 M at 25 °C. What is the concentration of hydronium ions in the solution? a. 3.2 × 1011 M b. 1.0 × 10–14 M c. 3.1 × 10–12 M d. 3.2 × 10–3 Marrow_forward6. What would the pH of a solution that had a hydroxide ion concentration of 2.3 x 107 M be? 7. What would the hydroxide ion concentration be if the hydrogen ion concentration was 6.8 x 10³ M?arrow_forwardCalculate how much volume of HCl you will to neutralize 8.900 g KOH. Density of HCl is 1.017 g/mLarrow_forward
- Write a balanced chemical equation to represent each of the following acid–base neutralization reactions. (Use the lowest possible coefficients. Omit states of matter.) Hl and NaOH HNO3 and RbOHarrow_forwardRemember in an acid-base reaction, there is only the movement of a hydrogen atom from the acid to the base. • When writing the reaction, be sure to use the correct arrow. How do you know if you need a single arrow pointing toward products or an equilibrium arrow? • Include the physical state of all reactants and products. 1. Write the reaction between an aqueous solution of HNO3 and water. Write the reaction using Lewis structures. 2. Write the reaction between an aqueous solution of CH3COOH and water. Write the reaction using Lewis structures. 3. Write the reaction between an aqueous solution of CH3NH2 and water. Write the reaction using Lewis structures. 4. Write the reaction between an aqueous solution of HCN and water. Write the reaction using Lewis structures. .arrow_forwardSome lemon juice has a hydronium ion concentration of 5.0 x 10-3 M. What is the pH of the lemon juice? Enter your answer to 1 decimal places.arrow_forward
