In Part C (Acid-Base Indicators) of the experiment, you are told to dispose of the used chemicals by pouring them into the sink. Consider the reaction that is possible between the used chemicals. What compound different from those in the used chemicals will be in the drain water as a result of this disposal?

a. HCL b. NaOH . c. NaCL

Explain your answer.

Answer #1

Answer is c. NaCl.

Because NaCl is salt and it can't respond to acid-base Indicators. NaCl is neutral salt and it will have pH 7.

HCl is acid so it responds to acid-base indicators.

NaOH is base so it responds to acid-base indicators.

This experiment is acid base indicator so netral salts are different from acids and bases. Because pH value is changed with concentration of acid and concentrationof base. pH does not change with concentrationof neutral salt.

Hence NaCl is different.

Acid-Base Behavior In addition to following the general safety rules, chemicals need to be handled properly. In particular, two very important classes of compounds called acids and bases require special attention. These compounds are commonly used reagents in the laboratory; therefore, understanding their proper disposal is beneficial. Physical differences between acids and bases can be detected by the some of the five senses, including taste and touch. Acids have a sour or tart taste and can produce a stinging sensation...

5. Compare the definition of a weak acid to the definition of a strong acid to explain why the reaction of acetic acid(HC2H3O2) (a weak acid)) with NaoH(a strong base) is less exothermic than the reaction between HCl(a strong acid) and NaoH. 6. A student carries out a calorimetry experiment using HCI and NaoH. What effect will each of the following have on the calculated enthalpy of the reaction relative to the actual enthalpy of reaction? (larger, smaller or no...
