Answer 1

1. (a). dropperful of 0.1 M calcium nitrate in a test tube, add a dropperful of 0.1 M sodium carbonate

Ca(NO3)2(aq) + Na2CO3(aq)    CaCO3(s)   +   2NaNO3(aq)

(b). a dropperful of 0.1 M magnesium sulfate in a test tube, add a dropperful of 0.1 M sodium hydroxide.

MsSO4(aq) + 2NaOH      Na2SO4(aq) +   Mg(OH)2(s)

(c). a dropperful of 0.1 M sodium nitrate in a test tube, add a dropperful of 0.1 M potassium chloride.

NaNO3(aq) + KCl(aq)      KNO3(aq) +   NaCl(s)

2. (a). a dropperful of 0.1 M NaOH and one drop of phenolphthalein. Add 0.1 M HCl drop by drop until the color changes.

HCl(aq) + NaOH(aq)     NaCl(aq) +   H2O(l)
