Question

Please answer them completely! thank you

a)A student was preparing an acidic salt solution using a solid salt.  How would the pH of the salt solution be affected (increase, decrease, or no change) if some solid salts were spilled on the bench top while it was being transferred into the volumetric flask?  Explain your reasoning.

b)A student was preparing a basic salt solution by diluting from a stock solution of the salt.  How would the pH of the salt solution be affected (increase, decrease, or no change) if the pipet was rinsed with distilled water but was not conditioned with the stock solution before use?  Explain your reasoning.

c)Baking soda contains NaHCO₃(sodium hydrogen carbonate or sodium bicarbonate).  A solution of baking soda can be ingested to alleviate acid indigestion. Based on what you learned from this lab, explain why it is an effective antacid.  Include chemical equations in your explanation.
