Lila tests the pH of 4 solutions. Which solution should she identify as being a base?
answers:
1. solution d
2. hydronium ion
3. feels slippery
4. vinegar
5. calcium carbonate
ic3peak is correct
mhm, thanks ic3peak!
so whats the answer?
Well, Lila certainly has some chemistry fun ahead! To determine which solution is a base, she should look for a high pH. If any of the solutions is singing "All About That Base," chances are that's the one she's looking for!
To identify which solution is a base, Lila needs to understand the pH scale. The pH scale ranges from 0 to 14, with values below 7 indicating acidity, a value of 7 indicating neutrality, and values above 7 indicating alkalinity or basicity.
To determine which solution is a base, Lila should use pH test strips or a pH meter to measure the pH of each solution. The pH test strips can be dipped into each solution, and the color change on the strip can be compared to a color chart to determine the pH value. Alternatively, a pH meter can be used, which gives a more precise numerical pH value.
If Lila finds that one of the solutions has a pH greater than 7, it would be classified as a base.
The one with a pH > 7.0
pH < 7.0 = acid
pH = 7.0 = neutral
pH > 7.0 = basic
