The minimum molarity for NaOH solution is 0.4 M .

If no NaOH is left after reaction, the maximum molarity of NaOH solution is 0.8 M .

Equal moles of ${\mathrm{NaHCO}}_3$ and ${\mathrm{Na}}_2{\mathrm{CO}}_3$ will form, if concentration of NaOH solution is 0.6 M .

If concentration of NaOH solution is $0.9\mathrm{M},0.3$ mole NaOH will left unreacted.
