Based on the parameters set forth in your lab procedure, what is the ph you should observe when you added the hcl to water?.
Rzqust [24]

Acid has a pH below 7 while water has a pH of 7. A strong acid with a pH of roughly 3, HCl is. Water gets more acidic and loses pH in the range of 4-5 when HCl is added to it.

<h3>What is pH?</h3>

A substance's pH is a gauge of how basic or acidic it is. It is a measurement of the amount of H+ present in the solution. It is equivalent to the negative logarithm of the concentration of H+ ions mathematically.

A solution is acidic if its pH value is less than 7, and basic if it is greater than 7. Acids have a lower pH because they contain more H+ ions. Strong acid hydrochloric acid has a pH between 2 and 3.

Water has no charge. Water becomes acidic in pH if any acid is introduced. Therefore, if HCl is given to water, the pH of the water will change to 3-5 depending on the acid content.

1. What is the relationship between ecological succession and equlibrium in an ecosystem?
alexandr1967 [171]

Answer:

Equilibrium in ecology refers to a state that occurs such that a small disturbance or change is counter balanced by another change so that the community is restored to its original state. Thus, as a community goes through multiple changes through each stage of succession, it is not in equilibrium.

shusha [124]
