Can you recommend safe reusable water bottles and tupperware? No glass please! Please provide a link to an online store where I can purchase, if you canThanks!
The best option for reusable water bottle is stainless steel, it is the only thing that is 100% not leaching, can be sterilized, won't react with acidic fluids like orange juice etcSigg had to change the lining of their aluminum bottles and now believe they are safeThere are a few plastics that are BPA free, but plastics break down over time, so I avoid themI'll put a link below that gives you several online retail optionsAs far as food storage, I primarily use glass it works in the oven and the freezerTupperware is considered safe, but you aren't supposed to heat most of itI never use plastic in the microwaveI also put the back to school link, which has info on reusable containers and links to the online stores.
Aluminium hydroxide is a saltRemember that a salt consists of Cations that transfer electrons to the Anions to form ionic bonds, with both cations and anions reaching noble gas structure In this case, when aluminium exists as a cation in salt, it has to transfer 3 electrons to the hydroxide in order to reach the noble gas structure Hence Al ions in AL(OH)3 is Al3+ since they've transferred away 3 negative electrons Hydroxide ions similarly gain electrons to reach noble gas structure and become OH- However they only need to gain 1 electron to achieve the structureSince, Al gives out 3 electrons, it would require 3 hydroxide ions to receive the 3 electronsHence Al+3(OH)Al(OH)3When naming compounds, first identify the cation (sodium,lithium,barium etc)Next identify the anion (nitrate,chloride,carbonate,hydroxide,fl To identify if an element is a metal, find out if it has a positive charge when it is in a salt such as aluminium 3+ ion is a metal but Chloride 1- ion is notGenerally, in salts, the metal will be written first such as NaOH, AlClMetals can also be found as single atoms due to their metallic bonds so metals can be written as Al or Fe, however non-metals cannot be found as a single atoms and form covalent bonds resulting in Cl2 or H2 or O2So you could easily identify metals
