正月初一或立春？

立春

題：農曆「新一年」到底是「立春」，抑或大年初一開始？香港天文台就特別公布正解，作為香港編算曆法的官方機構，天文台一直以農曆正月初一零時零分，作為農曆年的「干支交替時刻」，所以要去到下星期先至到辛丑年。

天文台解釋，我們平日講的「公元年」，源自西方基督教信仰為主的國家，以當時耶穌出生為紀年的開始，而中國傳統採用的是「干支」紀年，已經使用了超過2000年。翻查歷史，早於西漢時期，《史記.天宮書》已有記載，正月初一是官方一年首日，而二十四節氣則是用來劃分季節，「立春」就是春天之始。

「立春」。天文台在社交平台上發文指，立春是二十四四節氣之首、四時之始，象徵春天的來臨，按傳統曆法上，立春過後氣溫會逐步回升，春回大地。

calculate pH of phosphoric acid

Question: adding 1/4 teaspoon of 10% phosphoric acid to 19 litres of water, what will be the pH? Let's go through the calculations step by step. Step 1. Convert mass ( or volume) of 10% phosphoric acid to mole per litre ( mol/L) The above calculation shows that 1/4 tsp of H3PO4 acid is 6.97e-5 mol/L Step 2. Input this value to BATE (or other app) to calculate pH The answer: pH = 4.16, ie too acidic !? If you use pipette instead of teaspoon, 1 drop = 0.05ml. So 1/4 TSP means roughly 25 drops If you actually aim for pH 5.6 (which is optimum pH for mashing), conc will be 2.51 e-6, or 1/100 tsp , 0.044 ml, roughly 1 drop Let's roll back a bit. From recipes of BarleyWine , summer rye , hefe Gordon Strong suggested to use 1/4 teaspoon of 10% phosphoric acid, which is targeting pH of 5.5..... Discussion on homebrewtalk forum. However using online BF water calc , Sparge pH would be 4.6. but he also added 1 tsp of CaCl2. 2H20. Mash pH change from 5.7 t...
