No, $p H$ $pH$ is determined by measurement, and solely by measurement. However, it is probable that even $cupric hydroxide$ $"cupric hydroxide"$ , will have some solubility, enuff to elevate $p H$ $pH$ ABOVE $7$ $7$ .

Explanation:

$C u S O_{4} (a q) + 2 N a O H (a q) \to C u {(O H)}_{2} (s) ⏐ ↓ + 2 N a C l (a q)$ $CuSO_4(aq) + 2NaOH(aq) rarr Cu(OH)_2(s)darr + 2NaCl(aq)$

Your reaction does not include the correct states of the reactants, $cupric hydroxide$ $"cupric hydroxide"$ is quite insoluble in aqueous solution? $K_{sp}$ $K_"sp"$ $(C u {(O H)}_{2}) = 1.722 \times 10^{- 6}$ $(Cu(OH)_2)=1.722xx10^-6$ at $20$ $20$ $^{\circ} C$ $""^@C$ according to this [table.](https://en.wikipedia.org/wiki/Solubility_table)

How do we use the $K_{sp}$ $K_"sp"$ value to give a solubility in $g \cdot L^{- 1}$ $g*L^-1$ ?
