OWLV2 FOR MOORE/STANITSKI'S CHEMISTRY:
- The pH scale for acidity is defined by pH – log10 H*| where |H*| is the concentration of hydrogen ions measured in moles per liter (M). (A) The pH of Drano is 13.3. Calculate the concentration of hydrogen ions in moles per liter (M). [H*] = M (B) The pH of rain water is 5.5. Calculate the concentration of hydrogen ions in moles per liter (M). [H*] = Marrow_forwardArrange the following bases (in descending order) according to the volume of each that will react with 1 L of 1 M HCl (a) 1 M NaOH (b) 1.5 M Ca(OH)2 (c) 2 M KOH (d) 0.6 M Ba(OH)2arrow_forward4. How does the pH of each of the following solutions change when 5.0 mL of 1.0 M NaOH (a strong base) is added? Fill in the table. Give your answers with 2 decimals. Initial pH Final pH after adding NaOH Solution (a) 100.0 ml water (b) (c) 100.0 mL 0.150 M HNO2 (a weak acid) (Given: Ka = 4.5 × 10-4) 100.0 mL solution of 0.150 M HNO2 and 0.100 M NaNO₂arrow_forward
- What is the basis for referring to the hydrogen ion as a proton? (a) The Arrhenius definition of an acid. (b) The Brønsted-Lowry definition of an acid x (c) The Lewis definition of an acid. (d) H* exists as a bare proton. (e) None of these.arrow_forwardWhat is the molar hydronium ion concentration in solutions with each of the following pH values? (a) 1.0 [H3O+] = M (b) 5.0 [H3O+] = M (c) 9.0 [H3O+] = M (d) 12.0 [H3O+] = Marrow_forwardDetermine the pH of each solution and classify it as acidic,basic, or neutral.(a) pOH = 8.5(b) pOH = 4.2(c) pOH = 1.7(d) pOH = 7.0arrow_forward
- (a) Calculate the H3O™ concentration in an aqueous solution at 25°C with an OH concentration of 2.00 x 10 2 M. x 10 (b) The value of K at 100°C is 5.13 × 10¯13. Calculate the H20† concentration from the above solution at 100°C. x 10arrow_forwardA citrus tree can't get the nutrients it needs from the soil if its pH is above 6.5. (a) The hydrogen ion concentration of a soil sample is [H+] = 1.58 × 10−7 M. What is the pH of the soil? (Round your answer to one decimal place.)Is this soil suitable for citrus trees? Yes No (b) After the soil is amended, the pH is 5.6. Is the amended soil more acidic or less acidic than the original soil? more acidic less acidicarrow_forward10 mL of a solution of NaOH is found to be completely neutralized by 8 mL of a givensolution of HCl. If we take 20 mL of same solution of NaOH, the amount of HCl solution required to neutralize it will be:(a) 4 mL(b) 8 mL(c) 12 mL(d) 16 mLarrow_forward
- A student is provided with a 0.1 M stock solution of NaOH. Student was then asked to mix 50.0 mL of this stock solution of NaOH with 450.0 mL of water to prepare a dilute solution of NaOH. (A) Calculate the molarity of the diluted solution. (B). Calculate the hydronium ion concentration, [H3O+] in the final diluted solution. (8 points) (C ) Calculate the pH of the diluted NaOH solution. (D) Is the final diluted solution acidic, basic or neutral?arrow_forwardAnswer the following by selecting all correct answers. (a) Dynamic equilibrium O is a condition where two opposing processes are occurring at the same rate. O can only occur in water. O is used to describe what happens when weak acids or weak bases are added to water. O is used to describe what happens when strong acids or strong bases are added to water. (b) What will happen if acetic acid (HC2H3O2) is added to water?arrow_forwardA road tanker carrying an acid was involved in an accident and its contents spilledon the road, iron drain covers began melting and fizzing as the acid ran over them. ASpecialist was called to se if the acid actually leaked into the nearby river.(a) Explain how the specialist could carry out a simple test to see if the river water contains some acid or not.(b) The word melting is incorrectly used in the report. Suggest a better name that should have been used.(c) Explain why drain covers began fizzing as the acid rain over them.arrow_forward
