You might observe a fine white precipitate....

Explanation:

Metathesis of the salts occur to give moderately soluble $C a {(O H)}_{2} (s)$ $Ca(OH)_2(s)$ :

$C a {(N O_{3})}_{2} (a q) + 2 N a O H (a q) \to C a {(O H)}_{2} (s) ⏐ ↓ + 2 N a N O_{3} (a q)$ $Ca(NO_3)_2(aq) + 2NaOH(aq) rarr Ca(OH)_2(s)darr + 2NaNO_3(aq)$

$Calcium hydroxide$ $"Calcium hydroxide"$ is soluble in water to the tune of $1.73 \cdot g \cdot L^{- 1}$ $1.73*g*L^-1$ at $20$ $20$ $^{\circ} C$ $""^@C$ .
