% dissociation stays the same - Ka (dissociation constant) stays the same with concentration
1 M diluted to 0.1 M --> [H+] decrease by 10 times
-log[H+] = pH
log is base 10 so a change in [H+] of 10 means a change in pH of 1
pH will increase by 1
about the % dissociation im not sure what u meant to ask - if the value of Ka changes or if % dissociation changes, either way they both stay the same. HCl is a strong acid -> fully dissociates
