Solution

Yes. There are some hydrogen which are non replaceable.
For ex the reaction of sulphuric acid with base sodium hydroxide,
$H_{2} S O_{4} + N a O H \to N a H S O_{4} + H_{2} O H e r e b o t h h y d r o g e n s a r e n o t r e p l a c e d b y N a, s o t h e b a s i c i t y i s 1 . I f b o t h a r e r e p l a c e d, l i k e t h e f o l l o w i n g r e a c t i o n, t h e b a s i c i t y i s 2 . H_{2} S O_{4} + 2 N a O H \to N a_{2} S O_{4} + 2 H_{2} O$
