household ph up

I am out of baking soda and ph up and need an idea for anything I can find around the house that will do the job. Please help me out.

blood has a ph of 7.3-7.4 how bad do you want to ph up lol. is there a pet in the house or some one you don't like.

bar that hand soap has a ph of about 9 but that depends on brand and i don't know if it would be harm full to the plant
