<span>indicators are weak acids that exist as natural dyes and indicate the concentration of H+ (H3O+) ions in a solution via color change.</span>
Using this equation, we can take 25/(1.0 + 19) and find that it is equal to 1.25 moles.

Explanation:
The balanced chemical reaction is written as :
Na2CO3<span> + 2HCl === 2NaCl + H2O + CO2
</span>
We are given the amount of NaCl to be produced from the reaction. This will be the starting point for the calculations. We do as follows:
120 g NaCl ( 1 mol / 58.44 g) ( 1 mol Na2CO3 / 2 mol NaCl)( 105.99 g / 1 mol ) = 1108.82 g Na2CO3 needed
