Which of the following statements is true concerning acids and bases? acids and bases don't react with each other acids mixed with bases neutralize each other acids mixed with bases make stronger bases acids mixed with bases make stronger acids Correct Wrong Acids and bases interact with each other in what is called a neutralization reaction. The products of the reaction are a salt and water. The pH is "neutralized" to 7 if both the acid and base fully react. 2. True or false: bases are sometimes called alkalis. true false Correct Wrong Bases are alkaline and are sometimes called alkalis. Common alkali chemicals include laundry detergent, soap, and borax. 3. Which is the correct set of acid properties, as described by Boyle: sour taste, corrosive, change litmus from red to blue sour taste, corrosive, change litmus from blue to red sweet taste, slippery, change litmus from blue to red sour taste, slippery, change litmus from blue to red Correct Wrong There are several sets of definitions used to distinguish between acids and bases, but Boyle's method is easy and practical. Acids tend to be sour-tasting (don't taste them!), they are corrosive, and they turn litmus paper red. Bases are slippery-feeling, soapy-tasting, and turn litmus paper blue. 4. Neutral solutions have a pH of: 0 1 7 14 Correct Wrong Neutral pH is 7. An example of a neutral chemical is water. 5. An amphoteric substance can act as both an acid and a base. True or false? true false Correct Wrong An amphoteric or amphiprotic molecule can acts as either an acid or as a base, depending on its environment. Water is an example of an amphoteric molecule. 6. Which is true? pH of less than 7 is basic; pH of more than 7 is acidic pH of less than 7 is acidic; pH of more than 7 is basic Correct Wrong The pH scale runs from 1 to 14. Low numbers are acidic. pH of 7 is neutral. High values are basic. 7. Which substance completely dissociates in water? weak acids strong acids Correct Wrong Strong acids and strong bases completely dissociate into their ions in water. Hydrochloric acid (HCl) is an example of a strong acid. Sodium hydroxide (NaOH) is an example of a strong base. 8. According to the definitions of acids and bases devised by Lewis: acids are electron pair acceptors and bases are electron pair donors acids are electron pair donors and bases are electron pair acceptors Correct Wrong Lewis acids and bases are defined according to whether a chemical is an electron pair acceptor (acid) or electron pair donor (base). Other definitions involve protons and hydroxide ions. 9. A chemical species having one ionizable hydrogen ion is: monoprotic diprotic triprotic polyprotic Correct Wrong It's helpful to memorize the chemical prefixes mono- (one), di- (two), tri- (three), and poly- (many). A monoprotic acid is a compound that can only donate one proton or hydrogen ion in aqueous solution. An example is nitric acid. 10. Vinegar, fruit juice, and cola are examples of: strong acids weak acids strong bases weak bases Correct Wrong Fruit juices, soda, and vinegar are all examples of weak acids.
