Indicate if each of the following errors is systematic, random or human mistake based on how they affect the results of the lab: Group of answer choices Each solution absorbs carbon dioxide from the air, making them slightly more acidic [ Choose ] Estimating the amount of each salt to dissolve in the distilled water [ Choose ] Spilling some salt during the transfer into the centrifuge tube [ Choose ] Inconsistent volume in drops of indicator [ Choose ] Using dirty test tubes

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
