Na+ would be expected to have the largest radius because we are looking at the iconic signs and the Zeff which is the effective nuclear charge, for the ions. Magnesium has more proton than soduim so with the same numbers of electrons and 1s orbital shield, the Zeff for magnesium is greater and therefore Mg2+ has a smaller radius.
Answer:
Explanation:
Percent composition of sodium chloride .
NaCl
Mol weight = 23 + 35.5 = 58.5 g
58.5 g of NaCl contains 23 g of Na
100 g of NaCl contains 23 x 100 / 58.5 g of Na
= 39.3 %
Na = 39.3 %
58.5 g of NaCl contains 35.5 g of Cl
100 g of NaCl contains 35.5 x 100 / 58.5 g of Na
= 60.7 %
Cl = 60.7 % .

bromothymol blue is an indicator solution that is yellow in color for solutions with a pH of 6.0 or lower and blue in solutions with a pH of 7.6 or higher. Since citric acid is an acid, the pH was lower than 6.0 and the solution turned yellow. Pure citric acid has a pH of 2.2.</span>
