Vinegar is a liquid consisting of about 5–20% acetic acid(CH3<span>COOH),
</span>Sodium hydroxide<span> is a strong base. In concentrated form its pH can go up to somewhere in the region of 13-14
</span>The salts produced by the action of ammonia on acids are known as the ammonium salts and all contain the ammoniumion (NH4+). Although ammonia is well known as a weak base, it can also act as an extremely weak acid<span>.
</span>Water<span> acts as a base (accepts H+) when it reacts with a stronger </span>acid<span>, say hydrochloric </span>acid<span>. If the medium </span>is water<span>, </span>water<span>, having a pH of 7, is considered neutral. If the medium is ethanol (or any other solvent), </span>water<span> can be acidic, neutral or basic</span><span>
The atomic number of an element will tell you how many electrons it has in its ground state. The atomic number of boron is 5, therefore it has 5 electrons.
