Measurement of the pH of Rain

May 4, 2018BillLeave a comment

Today, with precipitation in the forecast, I set up my mini-laboratory to measure the pH of the local rainfall in Stormstown, PA. First, I installed a standard rain gauge to collect rainwater.

pH-1

I calibrated my pH meter, prior to taking any actual measurements, using standard reagents of pH of 4.0 and 6.86. I used a pH 7.0 reagent to verify.

pH-2

After calibration, I waited for some rainfall and then collected my sample.

P1030560

It had rained 0.20 inches over the past two days.

P1030561

This was about 400 ml of liquid.

P1030564

I measured the pH to be about 5.15, which is in the normal range for rainfall but still acidic. It is not considered to be acid rain.

The above is today’s upper level 300 mb chart. The 300 mb level, about 30,000 ft (9100 m) is where one would typically find the jet streams. The polar jet stream is clearly shown in the upper left portion of the chart. Arctic air has been dominating the northeastern US and is a reason for why the cold weather has been persisting this month.
