MT7628 是联发科技 2014 年底发布的业界新一代 2T2R 802.11n Wi-Fi AP/路由器系统单芯片解决方案(SoC)。这款全新 SoC 为智能家庭内的数据、语音和影像应用程序提供高数据传输率，而且耗电量远低于目前市场上其他同类产品。它和 MT7620 一样具有 2T2R 300M WiFi 速率，接口丰富，但是它比 MT7620 功耗更低、芯片成本更低，专门针对物联网应用推出 3个串口、PWM 输出等特点，可谓是 MT7620（2012 年发布）的升级产品。
MT7628 和同年发布的 MT7688（150M WiFi）是同一类芯片，两者管脚、软件几乎完全兼容。

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...
