There is an electrostatic force holding the electrovalent bonds together and they're usually structured, whereas in covalent, they are usually free and are only held together by a very weak intermolecular force
Answer:
Limitations of litmus paper and phenolphthalein:
They do not give the numerical pH value.
Can differentiate only between a very strong acid and base.
The colour change can be for reasons other than acid- base reactions.
Explanation:
The litmus test is quick and simple, but it suffers from a few limitations. First, it's not an accurate indicator of pH; it does not yield a numerical pH value. Instead, it roughly indicates whether a sample is an acid or a base. Second, the paper can change colors for other reasons besides an acid-base reaction.
Answer: By blowing into the drinking straw to bubble some of their breath in the water, they are adding gas to the water. This will cause the volume of gas to increase.
