The pH of a solution is tested and found to be 5.5. What can be concluded about the solution?

The correct answer is - option 1. the solution is acidic.

Explanation:

The pH is a scale to measure or check the acidity or basicity of an aqueous solution. The lower values on the pH scale indicate the acidity of the solution as on the pH bar 0 indicating the highest acidic value and the higher value indicates the alkaline or basic value of the solution and 14 indicating the highest alkaline. The pH of water is 7 which is a neutral condition.

Therefore, the pH of a solution with 5.5 on pH solution represents the acidic property of the solution, however, it is slightly acidic as it is near the neutral value.

The solution is acidic

Explanation:

The lower the number, the more acidic the solution is

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms

elements make up everything, and they combine to make compounds.

the answer is c
