A solution that is 4 on pH scale is an acid. A pH scale is used to measure whether a solution is an acid or a base. the pH scale is numbered between 0 to 14. 7 is the neutral point of this scale. Any solution having a pH of 7 is a neutral solution. Acidity of a solution increases as the reading in the scale decreases from seven towards zero. The basic nature of the solution increases as the pH level of the solution increases from 7 towards 14. The acidic nature of a solution having pH value of 3 is ten times more acidic than a solution having pH value of 4. The same thing is same while comparing basic solutions as well.

A pH scale runs from 1 to 14 with 7 being neutral.

1-6 has base like properties
8-14 has avid line properties

since this solution has a pH scale of 4.... the solution is basic

Electronegativities of the elements Na, Al, P, and Cl follow a specific trend across the period. Based on this trend, an electro
Vitek1552 [10]

Answer:

Electronegativity increases across the period on a periodic table.

Explanation:

Electronegativity is the ability of an atom to attract electron to itself.

All elements on the periodic table combines in order to have a complete octet i.e they all want to be like the noble gases, group 0 elements.

This is what drives most atom to combine chemically. By so doing, they either lose or gain electrons.

Cl belongs to the 7th group on the periodic table. It is the second element in this halogen group. Most halogens are notable for their high electronegativity. They have 7 electrons in their outermost shell and would require just an electron to complete their octet.

This makes them highly reactive and combine readily with other elements.

The halogens have a strong attraction for valence electrons. The higher the electronegativity value, the stronger the attraction an atom has for valence electrons.

Most metals like Al and Na are electropositive and readily donates or lose electrons so as to have a complete octet.

How can we reduce the production of harmful gases that form acid rain
oksano4ka [1.4K]

Answer:

A great way to reduce acid rain is to produce energy without using fossil fuels. Instead, people can use renewable energy sources, such as solar and wind power. Renewable energy sources help reduce acid rain because they produce much less pollution.
