Descripción
Innovating Science acid, bases, and pH scale kit helps students determine the differences between acid and base properties, the role of hydrogen and hydroxide ions in acids and bases, and the relationship of the pH scale to acid and base strength. The kit’s activities cover examining the effects of acids and bases on several chemical pH indicators, identifying the pH of common household materials, and determining the composition of four unknown clear solutions. For hands-on learning, the kit has materials for 15 groups of students, including deionized water, dilute acid, base, litmus, methyl red, bromothymol blue, phenolphthalein, vinegar, household ammonia, soap, filtered water, vitamin C solution, pH test strips, unknown solutions, and reaction trays. The kit has a teacher’s manual and student study guide copymasters for instructional use, and a material safety data sheet (MSDS) packet for product information and handling procedures. The kit is suitable for age 13 and older with adult supervision, and meets the requirements for Department of Transportation (DOT) small quantity exemption 173.4, and conforms to 49 Code of Federal Regulations (CFR) 173.4 for domestic highway or rail transport only.Science education products incorporate applied math and science principles into classroom and homeschool-based projects. Teachers in pre-K, elementary, and secondary classrooms use science education kits and products alongside science, technology, engineering, and math (STEM) curriculum to demonstrate STEM concepts and real-world applications through hands-on activities. Science education projects include a broad range of activities, such as practical experiments in engineering, aeronautics, robotics, energy, chemistry, physics, biology, and geology.Innovating Science products, manufactured by Aldon Corporation, include educational kits for the chemistry, life science, green chemistry, advanced placement chemistry, and forensic fields. Aldon Corporation was founded in 1964, and is headquartered in Avon, NY.What’s in the Box?(1) deionized water (25.0mL)(1) dilute acid-0.1M HCl (25.0mL)(1) dilute base-0.1M NaOH (25.0mL)(1) 0.5% litmus (25.0mL)(1) 0.02% methyl red (25.0mL)(1) 0.5% bromothymol blue (25.0mL)(1) 1.0% phenolphthalein (25.0mL)(1) vinegar (25.0mL)(1) household ammonia (25.0mL)(1) soap solution (25.0mL) (1) filtered water (25.0mL)(1) vitamin C solution (25.0mL)(2) wide-range pH test strips (package of 50)(1) unknown solution #1 (water) (25.0mL)(1) unknown solution #2 (dilute base) (25.0mL) UN1824(1) unknown solution #3 (phenolphthalein) (25.0mL) UN1219(1) unknown solution #4 (dilute acid) (25.0mL)(15) reaction traysTeacher’s guideStudent study guide copymastersMaterial safety data sheet (MSDS) packet
