Module 10 Science Journal Lesson 1 Practice 1 – Acids and Bases Tutorial 1. An unknown chemical feels slippery and litmus paper turns blue when dipped in the liquid. This liquid is a _base__ . 2. How does Arrhenius define an acid? Bases are hydroxide chemicals that produce OH- ions, whereas acids are hydrogen-containing compounds that produce H+ ions. 3. What is neutralization? When an acid and a base react to form a salt and water 4. What will the neutralization of an acid with a base always produce? salt and water 5. What is the chemical equation for pH? pH = −log [H+] 6. Name two acids and two bases. Two acids: hydrochloric acid (HCl) and nitric acid (HNO3) Two bases: ammonia (NH3), potassium hydroxide (KOH) 7. Complete the interactive quiz and record your score here: Lesson 1 Practice 2 – Theory and Naming Practice After checking your answers … 1. How are acids and bases different?
Hydrogen (H+) or hydronium (H3O+) in a solution is an acid. They react to metals, turning litmus red and phenolphthalein transparent, and have a pH of less than 7. Hydroxide ions (OH+) in a solution are known as bases.They color litmus blue and phenolphthalein pink, are slick, and have a pH greater than 7. They also don't react to metals. 2. Explain how you name an acid. An acid is named as [H + one other element], where "hydro" is the starting point, the element's name's root is used, and the suffix "ic" or [H + polyatomic ion] is added. If the polyatomic ion had a "-ate" ending, add the suffix "ic," and if it had a "ite" ending, add the suffix "ous." Lesson 2 Practice 1 – pH Interactivity Paste your completed pH calculation table below:
Lesson 3 Practice 1 – Interactive Acid/Base Titration Practice 1. What were the three basic steps to answer Problem #1? Determine the key molar ratio, determine the moles of HCl and NaOH, and determine the molarity of NaOH solution. 2. Explain the steps used to complete Problem #4. Step 1: Write out the chemical reaction Step 2: Find the moles in H2SO4 by dividing the 75 mL by 0.500 M H2SO4 Step 3: Since two moles have to be neutralized in the example, multiply the sum from step 2 by two. Step 4: Calculate the volume by dividing moles by molarity. You will submit this Science Journal as a grade in the course.
