Is it safe to pour sulphuric acid down the sink? Caustic soda was put down about 1 week ago?

We have a drain blockage and someone put caustic soda down the drain about 6 days ago. Do you think it will be safe to put sulphuric acid drain cleaner down there by now? Because you aren't supposed to mix sulphuric acid and caustic soda

Update:

Sink blockage, not drain. The blockage is quite far down. About 3 meters

    To be correct you should not pour sulphuric acid down any drain,it seems as though you know where the blockage is, 3 meters away sound more like a drain than a sink to me.

    I don't see the reason for trying sulphuric acid as it wont actually clear away any fatty gunge etc.you really need to rod it or constantly plunge to get rid of the blockage
