Which is the common ion when sodium sulfate is added to a solution of barium sulfate? na + ba 2+ so4 2 –?

The compound sodium sulfate is made of sodium ion and sulfate ion.

The formula can be written as Na₂SO₄.

The cation present in this compound is Na⁺ and the anion is SO₄²⁻.

The compound barium sulfate is made of barium ion and sulfate ion.

The formula can be written as BaSO₄.

This compound contains the cation Ba²⁺ and anion SO₄²⁻.

From the above , we can see that both the compounds have common anion which SO₄²⁻

So, the sulfate, SO₄²⁻ is the common ion when sodium sulfate is added to a solution of barium sulfate

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

hope this mark me brainliest
