Hello, I am Sara and I am living in Haifa. I measured pH from tap-water at my home. The water had a constant pH value for some days : pH=7.4 In the following picture you may get an impression on how I monitored pH value by using tap water, litmus drops and pH color card .
Measurement accuracy is according to pH color card ≤0.4. It was interesting for me to pick out water pH values at home. Enjoy your study. Regards, Sara.
