    2NaOH + CO2 → Na2CO3 + H2O

    Yet this turns universal indicator orange, more of an acid. Would carbonic acid be formed?

    I think, not sure though, that another reaction takes place after the reaction stated above, like Ca(OH)2 + CO2, namely

    2NaOH + CO2 → Na2CO3 + H2O

    Na2CO3 + CO2 + H2O → 2NaHCO3

    Which may be acidic.

    Yes Carbonic acid is formed. If NaOH is aqueous at the time of reaction, the initial reaction would be
    CO2 + H2O → H2CO3

    Which goes on to combine with NaOH to form the hydrocarbonate
    NaOH + H2CO3 → NaHCO3 + H2O

    The hydrocarbonate further reacts with sodium hydrocarbonate to form the carbonate
    NaHCO3 + NaOH -> Na2CO3 + H2O

    The reaction is self sustaining as long as NaOH molecules remain, because the water molecules formed as by-products of the reactions would continuously combine with CO2, which is always readily available. That's why the universal indicator is turning orange, because the products left after while is the salt (Na2CO3) and the weak acid (H2CO3)
