(d) Write the net ionic equation for the neutralization of perchloric acid with ammonia in this solvent.arrow_forwardIn Arrhenius acidbase theory, what ion is responsible for the properties of a. acidic solutions b. basic solutionsarrow_forwardA 10.0-mL sample of an HCl solution has a pH of 2.000. What volume of water must be added to change the pH to 4.000?arrow_forward
- Follow the instructions of Question 7 for the hydrogen carbonate ion, HCO3-.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_forwardDetermine from the following molecular view of a hydrofluoric acid (HF) solution whether HF is a strong or a weak acid:arrow_forward
- You are asked for the H+ concentration in a solution of NaOH(aq). Because sodium hydroxide is a strong base, can we say there is no H+. since having H+ would imply that the solution is acidic?arrow_forwardConsider two beakers of pure water at different temperatures. How do their pH values compare? Which is more acidic? More basic? Explain.arrow_forwardA base is a substance that dissociates in water into one or more ______ ions and one or more ________. a.hydrogen . . . anions b.hydrogen . . . cations c.hydroxide . . . anions d.hydroxide . . . cationsarrow_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_forwardDifferentiate 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_forwardArrange the following 0.10 M aqueous solutions in order of increasing pH: HF, NaF, HNO3, and NaNO3.arrow_forward
