NaOH is the Answer.

Explanation:

By criss crossing the charge numbers, we find the chemical formula of a compound

For example Aluminium chloride

Al has 3+ charge and Cl has 1- charge

3 becomes the subscript of Cl and 1 becomes the subscript of Al

So the chemical formula will be Al_1 Cl_3

Sodium Hydroxide is NaOH as Na the charge is 1^+ and as OH, the charge is 1^-

Sodium phosphate is Na_3 PO_4 as sodium has 1^+ charge and phosphate has PO_4^3- charge.

Sodium sulfate is Na_2 SO_4 as sodium has 1^+ charge and sulfate has SO_4^2- charge.

Sodium chloride will be NaCl as sodium has 1^+ charge and chloride has 1^- charge.

Calcium phosphate will be Ca_3 (PO_4 )_2 because Calcium possess 2^+ charge and phosphate has PO_4^3- charge.
