So, it should be maintained to prevent UTI. 2. The pH of urine may affect the antimicrobial activity of the antibiotics used for treating UTI. WebVandaag · Salts of the weak acid and strong base are alkaline i.e. having pH > 7 As discussed before NaHCO3 is the salt of sodium hydroxide and carbonic acid which are strong base and weak acid, respectively. This makes NaHCO3 alkaline having a pH value of more than 7. Why does the aqueous solution of NaHCO3 become basic?
