- Write equations that show H2PO4- acting both as an acid and as a base.arrow_forwardClassify each of the following as a strong acid, weak acid, strong base, or weak base in aqueous solution. a. HNO2 b. HNO3 c. CH3NH2 d. NaOH e. NH3 f. HF g. h. Ca(OH)2 i. H2SO4arrow_forward(a) What is the pH of a 0.105 M HCl solution? (b) What is the hydronium ion concentration in a solution with a pH of 2.56? Is the solution acidic or basic? (c) A solution has a pH of 9.67. What is the hydronium ion concentration in the solution? Is the solution acidic or basic? (d) A 10.0-mL sample of 2.56 M HCl is diluted with water to 250. mL What is the pH of the dilute solution?arrow_forward
- Without writing an equation, specify the molecular ratio in which each of the following acidbase pairs will react. a. HNO3 and NaOH b. H2SO4 and NaOH c. H2SO4 and Ba(OH)2 d. HNO3 and Ba(OH)2arrow_forwardWrite equations that show NH3 as both a conjugate acid and a conjugate base.arrow_forwardConsider the following four solutions: (1) apple juice, pH 3.8, (2) pickle juice, pH 3.5, (3) carbonated beverage, pH 3.0, and (4) drinking water, pH 7.2. a. Which solution has the highest [H3O+]? b. Which solution has the highest [OH]? c. List the solutions in order of increasing acidity. d. List the solutions in order of decreasing basicity.arrow_forward
- Which of the following substances are acids in terms of the Arrhenius concept? Which are bases? Show the acid or base character by using chemical equations. a P4O10 b Na2O c N2H4 d H2Tearrow_forwardWrite a balanced chemical equation to represent each of the following acidbase neutralization reactions. a. HCl and NaOH b. HNO3 and KOH c. H2SO4 and LiOH d. Ba(OH)2 and H3PO4arrow_forwardFind [H+] and the pH of the following solutions. (a) A 456-mL sample of a 12.0% (by mass) solution of HNO3(d=1.00g/mL). What is the pH of 10.0 mL of the same sample? (b) A solution made up of 1.0 g of HCI dissolved in enough water to make 1.28 L of solution. What is the pH of the solution? If the same mass of HCI is dissolved in enough water to make 128 mL of solution, what would the pH be?arrow_forward
- Differentiate between the terms strength and concentration as they apply to acids and bases. When is HCl strong? Weak? Concentrated? Dilute? Answer the same questions for ammonia. Is the conjugate base of a weak acid a strong base?arrow_forwardMost cola soft drinks have a pH of 3.1. Green tea has a pH of 5.8. (a) Calculate [H+] for the cola soft drink and green tea. (b) How much more acidic is a cola soft drink than green tea? Express your answer as a ratio of [H+] (cola) to [H+] (green tea).arrow_forwardWhat is meant by “pH”? True or false: A strong acid always has a lower pH than a weak acid does. Explain.arrow_forward
