#[H^+]=10^(-6.6)# #mol*L^-1#

Explanation:

#pH=-log_10[H^+]# by definition.

If #pH=6.6#, then to get #[H^+]# we take the antilogarithm:

#[H^+]# #=# #10^(-6.6)# #mol*L^-1# with respect to #H^+# or #H_3O^+#, an equivalent representation.

This solution is very slightly acidic. I don't think you could taste the difference.
