Why does the height of the precipitate of strontium nitrate and sodium carbonate go up as the volume of strontium nitrate increase?
More SrNO3 was needed to complete the reaction precipating SrCO3.

The height of the precipitate of strontium nitrate and sodium carbonate increases as the volume of strontium nitrate increases because of a reaction called a precipitation reaction. In a precipitation reaction, two solutions are mixed together to form a solid, insoluble product called a precipitate.
To understand why the height of the precipitate increases with the volume of strontium nitrate, we need to consider the chemical reaction that occurs between strontium nitrate and sodium carbonate. The balanced chemical equation for this reaction is:
Sr(NO3)2(aq) + Na2CO3(aq) -> SrCO3(s) + 2NaNO3(aq)
In this equation, "Sr(NO3)2" represents strontium nitrate, "Na2CO3" represents sodium carbonate, "SrCO3" represents strontium carbonate (the precipitate), and "NaNO3" represents sodium nitrate (the remaining aqueous solution).
When the two solutions are mixed, the strontium nitrate and sodium carbonate ions interact to form solid strontium carbonate and sodium nitrate. The sodium nitrate remains dissolved in the solution, while the strontium carbonate is insoluble and precipitates out as a solid.
As the volume of the strontium nitrate solution increases, there are more strontium ions available to react with carbonate ions from the sodium carbonate solution. This higher concentration of reactants leads to a greater number of precipitate particles being formed, and therefore, an increase in the height of the precipitate.
In summary, the height of the precipitate of strontium nitrate and sodium carbonate increases as the volume of strontium nitrate increases because a higher volume provides more strontium ions, leading to a more extensive precipitation reaction and a greater amount of solid strontium carbonate precipitate being formed.
