For sure . . . any soda will kill sperm. Some women have used soda in their birth canals to kill sperm there, and keep from being pregnant. A large number of these women die from it.
No, blood will not kill any sperm inside a woman's vagina. At most, the flow will flush out the remaining sperm over time, but do not plan on it. However, if you had unprotected sex you could get pregnant.
the sperm inside the condom cannot impregnate you. However if there is a hole or split in the condom the sperm that escapes can. Although condoms are coated in spermicide it will not kill all of the sperm.

Women's vagina's vary in their pH balance. A very acidic vagina can kill sperm. Normally at the time of ovulation, a woman's pH becomes neutral, allowing sperm to survive. Also, a man's ejaculate is alkaline, so when combined with an acidic vagina this creates a neutral environment. Some women are very acidic and find it difficult to get pregnant. Also, some women have an overactive immune response to sperm and their immune systems kill off and attack the sperm cells, also some women have this response to an early pregnancy and their own bodies terminate the pregnancy. Both of these are considered to be very rare.
Douching, even with a spermicidal solution, will only eliminate sperm in the Vagina, it will not affect any that have already entered the Uterus. Generally, douching is a very tiresome way of getting pregnant and an ineffective means of contraception.
That is not how an IUD works. What an IUD do is to stop an egg from attaching to the inside of the uterus. It had no effect on the sperm. But no, it shouldn't hurt.
